Question

What is the value of x?
Please help. I will reward for correct answers.

Answer 1

x = 7

Explanation:

Corresponding parts of the similar triangles are proportional. The bottom left part is 8 times the length of the top left part, so the bottom right part will be 8 times the length of the top right part:

2x +10 = 8·3

x +5 = 12 divide by 2

x = 7 subtract 5
