Someone please help me before I frl cry

Anna71 [15]

Answer:

Equation: 4x = 128

$m\angle 1 = 84\degree$

$m\angle 2 = 96\degree$

Step-by-step explanation:

$m\angle 1+ m\angle 2 =180\degree$ (Linear pair angles)

-> (x + 52)° + (3x)° = 180°

-> (4x + 52)° = 180°

-> 4x + 52 = 180

-> 4x = 180 - 52

-> 4x = 128 ( This is the required equation)

-> x = 128/4

-> x = 32

$m\angle 1 = (32+52)\degree = 84\degree$

$m\angle 2 = (3*32)\degree = 96\degree$
