Answer:
Step-by-step explanation:
- Use ratios to solve for x. Corresponding sides have same ratio.
Q1
- (x + 5)/30 = (36 - 20)/20
- (x + 5)/30 = 16/20 = 4/5
- 5(x + 5) = 4(30)
- 5x + 25 = 120
- 5x = 95
- x = 19
Q2
- (5x - 2)/(3x + 1) = 39/26
- (5x - 2)/(3x + 1) = 3/2
- 2(5x - 2) = 3(3x + 1)
- 10x - 4 = 9x + 3
- 10x - 9x = 3 + 4
- x = 7
TS = 3x + 1 = 3(7) + 1 = 22
