Question

Pls help I dont know how to do this​

Answer 1

• 1. CE = 63
• 2. x = 16

Explanation:

Use proportions to solve.

Corresponding sides have same ratio.

Question 1

• DE/EG = CE/EF

• (6x + 3)/17 = (8x - 1)/21
• 21(6x + 3) = 17(8x - 1)
• 126x + 63 = 136x - 17
• 10x = 80
• x = 8

• CE = 8*8 - 1
• CE = 63

Question 2

• KM/MD = KZ/ZH

• (x + 8)/21 = 32/28
• x + 8 = 21*8/7
• x + 8 = 24
• x = 24 - 8
• x = 16
