x = 50

The angles shown are vertically opposite and thus equal

so 3x - 30 = 2(x + 10)

3x - 30 = 2x +20

subtract 2x from both sides

3x - 2x - 30 = 20

x - 30 = 20

add 30 to both sides

x = 20 + 30 = 50

Can anybody help me with this question please ?

Answer:

x = 8.75, y = 8.125

Step-by-step explanation:

The triangles are similar thus the ratios of corresponding sides are equal, that is

$\frac{8}{5}$ = $\frac{14}{x}$ ( cross- multiply )

8x = 70 ( divide both sides by 8 )

x = 8.75

And

$\frac{8}{5}$ = $\frac{13}{y}$ ( cross- multiply )

8y = 65 ( divide both sides by 8 )

y = 8.125
