answer is c
Step-by-step explanation:
The degree of a line is 180, so..
Put it into an equation form: 5x + 75 = 180
1st combine like terms by subtracting 75 from 180
now your equation looks like this: 5x = 105
next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21

Answer:
4.8ft
Step-by-step explanation:
The perimeter solved shows that the dimensions of the rectangle are 32 and 10.
<h3>How to calculate the perimeter</h3>
Let the width be w
Length = 3w + 2
Perimeter = 2(length + width)
Perimeter = 2(3w + 2) + 2w
6w + 4 + 2w = 84
8w + 4 = 84
8w = 84 - 4
w = 80/8
w = 10
Length = 3w + 2
Length = 3(10) + 2
Length = 32
The dimensions of the rectangle are 32 and 10.
