Answer:
x = 4
Step-by-step explanation:
(5x+131)° and (5x+19)° are supplementary. Therefore, (5x+19)° + (5x+131)° equals to 180°.
Knowing that, we can do the following:
- (5x+19) + (5x+131) = 180
- 5x + 19 + 5x + 131 = 180
- 10x + 140 = 180
- 10x = 40
- <em>x = 4</em>
The volume of the prism is 9 in³.
<h3 /><h3>What is a prism?</h3>
A prism is a 3-dimensional shape, with two identical shapes facing each other.
To calculate the volume of the prism, we use the formula below.
Formula:
- The volume of the prism (V) = 72×volume of one cube
- V = 72L³............. Equation 1
Where:
- V = Volume of the prism
- L = Length of the cube
From the question,
Given:
Substitute these values into equation 1
- V = 72(1/2)³
- V = 72(1/8)
- V = 9 in³
Hence, the volume of the prism is 9 in³.
