Answer:
b= 70
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to exterior angle.
a+b = 140
We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal
b+b = 140
2b =140
Divide by 2
2b/2 =140/2
b= 70

Answer:
17 ft, 27 ft, 20 ft
Step-by-step explanation:
Let s represent the length of the shortest side. The the longest side is (2s-7) and the third side is (s+3). The perimeter is the sum of the side lengths:
64 = s +(2s -7) +(s +3)
64 = 4s -4 . . . . . . . . . . . collect terms
16 = s -1 . . . . . . . . . . divide by 4
17 = s . . . . . . . . . add 1
2s -7 = 2·17 -7 = 27 . . . . . the length of the longest side
s +3 = 17 +3 = 20 . . . . . . . the length of the third side
The side lengths are 17 feet, 27 feet, and 20 feet.
