Question

Definitely could use some help. Would also be really appreciated if someone gave a breakdown of how they solved it. Thank you!!!

Answer 1

• x = 10

Explanation:

Parallel lines cut the transversals into proportional sections.

Find the ratios of the corresponding parts and solve for x:

• (3x - 5)/(28 - 8) = 10/8
• (3x - 5)/20 = 5/4
• 3x - 5 = 20*5/4
• 3x - 5 = 25
• 3x = 30
• x = 10
