Answer 1

saw a 1 star review so I decided to add my own answer
Answer:

20

Explanation:

The top triangle has lengths 11, 10, and p ( unknown p ). We can form a larger triangle by including the bottom half. This now becomes a triangle with sides 132 and 5x + 20. Following ratios 11:10 must be equal to 132:5x+20. 132 = 11 * 12

By the ratio 5x+20 = 10 * 12

Or 5x + 20 = 120 or 5x = 100 or x = 20

Answer 2

x=18

Explanation:

11×11= 121

10×10=100

so, 5x+10=100

5x=90

x=18
