Answer 1

Explicación paso a paso:

Numeral 1

$m = 50 + 30$

$m = 80$

$x + m + 60 = 180$

$x + 80 + 60 = 180$

$x = 180 - 80 - 60$

$x = 40$

Numeral 2

$2θ + θ + θ = 180$

$4θ = 180$

$θ = \frac{180}{4}$

$θ = 45$

_______________________________________

Numeral 3

$x + x + 24 = 180$

$2x + 24 = 180$

$2x = 180 - 24$

$2x = 156$

$x = \frac{156}{2}$

$x = 78$

Numeral 4

$3θ + 2θ + 45 = 180$

$5θ + 45 = 180$

$5θ = 180 - 45$

$5θ = 135$

$θ = \frac{135}{5}$

$θ = 27$
