Answer:
x = 28
Step-by-step explanation:
The sum of the angles in a straight angle = 180°
Sum the angles and equate to 180
2x + 20 + 3x + 20 = 180
5x + 40 = 180 ( subtract 40 from both sides )
5x = 140 ( divide both sides by 5 )
x = 28
Answer:
The width is 10 inches
Step-by-step explanation:
Perimeter = 2(Length + Breadth)
Length(L) = 3B + 5
Perimeter = 70
70 = 2(3B + 5)
70 = 6B + 10
70 - 10 = 6B
60 = 6B
60/6 = B
B = 10 inches
