Triangle ABC has side lengths 8 cm, 17 cm, and x cm. The side length of x is shorter than the longest side. What does the value of x need to be in order for the triangle to be considered a right triangle?
Answer:
8 cm and 15 cm
The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm
What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle BC = 8 cm
The height of the triangle be AB = x cm
The hypotenuse of the triangle AC = 17 cm
So , for the triangle to be a right angle triangle ,
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
AC² = AB² + BC²
So , AB² = AC² - BC²
On simplifying the equation , we get
AB² = 17² - 8²
AB² = 289 - 64
AB² = 225
Taking square roots on both sides of the equation , we get
AB = 15 cm
Therefore , the value of x is 15 cm
Hence , The measure of the side is 15 cm
The measure of the right angle triangle is 8 cm, 15 cm and 17 cm

Multiply 3 3/8 • 4 1/3
Answer:
14 5/8
Step-by-step explanation
1) Convert the mixed number to an improper fraction
3 3/8 = 3 x 8 + 3 / 8 = 24 + 3/ 8= 27/8
2) Convert the second mixed number to an improper fraction
4 1/3 = 4 x 3 + 1/ 3 = 12 + 1/3= 13/3
3) Multiply 27/8 x 13/3= 351/24 divided by 3 = 117/8 117/8 as a mixed number is 14 5/8
4) 14 5/8 is the final answer simplified
Answer:
[tex]\frac{117}{8}[/tex] (or [tex]14\frac{5}{8}[/tex] in mixed number form)
Step-by-step explanation:
1) First, convert [tex]3\frac{3}{8}[/tex] and [tex]4\frac{1}{3}[/tex] into improper fractions. (Multiply the denominator by the whole number at the front, then add the numerator. The number that you receive from this would be the new numerator, and the denominator would still be the same.) This would be [tex]\frac{27}{8}[/tex] and [tex]\frac{13}{3}[/tex] respectively.
2) Multiply the two improper fractions. Multiply the numbers of the numerators and denominators together:
[tex]\frac{27}{8}[/tex]·[tex]\frac{13}{3}[/tex]
[tex]\frac{351}{24}[/tex]
3) Simplify the fraction. Find a number that both 351 and 24 can divide evenly into - in this case, it is 3. Divide both 351 and 24 by 3 and receive the final answer:
[tex]\frac{351}{24}[/tex]÷[tex]\frac{3}{3}[/tex]
[tex]\frac{117}{8}[/tex]
If you need it in mixed number form, find what times 8 can get closest to the number 117 without going over it. In this case, it is 14, since 14 times 8 is 112, and 112 is the biggest number closest to 117 that is still under it. 14 would be the whole number at the front Include the remainder, or how far away 112 is from 117, which is 5, at the numerator. The denominator would stay the same. Therefore, the answer in mixed number form is [tex]14\frac{5}{8}[/tex].

A company purchased equipment for $150,000 by paying $50,000 and signing a $100,000 note payable. The entire $150,000 is reported as a cash outflow in the financing section of the statement of cash flows.
Answer: False
Step-by-step explanation:
The financing section deals with only the transactions that have to do with equity and debt. The Investing section deals with capital expenditure such as fixed assets and investments in other company securities.
The $50,000 should therefore be recorded in the Investing section as a Cash outflow.
The $100,000 is not a cash transaction but will be recorded in the Notes to the Statement of Cashflows as a Non-Cash transaction for disclosure purposes.
How much paint does Brielle need to finish her room
Answer:
Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.
Step-by-step explanation:
As, this question is incomplete, so we will create similar question and complete it. '
Let's suppose Brielle's room has following dimensions:
Length of two walls = 10 ft
Length of other two walls = 12 ft
Height of the room from bottom to ceiling = 10 ft
In order to calculate the amount of paint needed, we need to calculate the surface area of the room to be painted.
So, for that, add all the lengths together and multiply it by height of the room.
SF = (L1 +L2 +L3+ L4) x H
SF = (10 + 10 + 12 + 12) x (10)
SF = 440 sq.ft = Actual footage of the room to be painted.
Now, we have convert this number in gallons to know the amount of paint required to paint Brielle's room. For this, we need to divide our SF to 350 sq.ft per gallon.
Paint Needed = 440 sq.ft / 350 sq.ft per gallon
Paint Needed = 1.25 gallons = It means 1 gallon and 1 quart of paint is needed to paint the Briellie's room.

in exercise 4 and 5 find the unkown or marked angles
Answer:
Ф = 110°, β = 110°
Step-by-step explanation:
∠Ф and the 110° angle are corresponding angles since the vertical lines are parallel and a horizontal line cut across both lines. Thus Ф = 110°.
∠β and ∠Ф are alternate angles since the horizontal lines are parallel and a vertical line cut across both lines. Thus Ф = 110° and ∠β = 110°.

Lillian thinks that 725 - 4x3 is the same as 3.22. Which statement shows that it is
NOT the same?
Answer:
The correct option is (c).
Step-by-step explanation:
Lillian thinks that 7x⁵ - 4x³ is the same as 3x².
Option (a) :
7x⁵ - 4x³ = 3x²
It is wrong, as we cannot say directly that they are equal.
Option (b):
7x⁵ - 4x³ ≠ 3x²
It is wrong, as we cannot say directly that they are not equal.
Option (c):
7(2)⁵ - 4(2)³ = 3(2)²
LHS,
7(32) -4(8) = 192
RHS, 12
Here, LHS ≠ RHS
It is correct.
Option (d) :
7(2)⁵ × 4(2)³ = 3(2)²
Here, multiplication is done instead of addition. So, it is wrong.
Hence, the correct option is (c).
