Answer 1

Resposta:

$\text{Leia abaixo}$

Explicação passo-a-passo:

Ângulos complementares somam 90°.

$3x + 30 + 2x + 10 = 90$

$5x + 40 = 90$

$5x = 90 - 40$

$5x = 50$

$x = \dfrac{50}{5}$

$\boxed{\boxed{x = 10}}$

$\text{A} = 3(10) + 30$

$\text{A} = 30 + 30$

$\boxed{\boxed{\text{A} = 60\textdegree}}$

$\text{B} = 2(10) + 10$

$\text{B} = 20 + 10$

$\boxed{\boxed{\text{B} = 30\textdegree}}$
