Answer 1

Answer:

x = 5

Step-by-step explanation:

The 2 triangles are similar by the AA postulate then the ratios of corresponding sides are equal , that is

$\frac{x+x+10}{30+10}$ = $\frac{x+10}{30}$

$\frac{2x+10}{40}$ = $\frac{x+10}{30}$ ( cross- multiply )

30(2x + 10) = 40(x + 10) ← distribute parenthesis on both sides

60x + 300 = 40x + 400 ( subtract 40x from both sides )

20x + 300 = 400 ( subtract 300 from both sides )

20x = 100 ( divide both sides by 20 )

x = 5
