Answer:

  • x = 19, TS = 22

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
