Question

calcula el valor de x y los angulos señalados​

Answer 1

Respuesta:

(a)

x = -4

α = 172°

β = 8°

(b)

x = 5

α = 28°

β = 28°

Explicación paso a paso:

(a)

2x + 180 + x + 12 = 180

3x = -12

x = -4

-------

α = 2(-4) + 180 = 172°

β = - 4 + 12 = 8°

(b)

6x - 2 = 2x + 18

4x = 20

x = 5

----

α = 6(5) -2 = 28°

β = 2(5) + 18 = 28°
