Question

Solve similar triangles (advanced) Solve for x A, 3, B^2, x, D, 13, E, C

Answer 1

Answer:

x = 10

Step-by-step explanation:

$\frac{3}{13}$ = $\frac{3}{3+x}$  cross multiply and solve for x

3(3+ x) = 3(13)  Distribute the 3

9 + 3x = 39  Subtract 9 from both sides

3x = 30  Divide both sides by 3

x = 10
