olga_2 [115]

Answer:

Step-by-step explanation:

Using the angle addition postulate

angle 1+angle 2+angle 3=180

Angle 2 is 90 degrees,

Angle 1 is 2x degrees

Angle 3 is 3x degrees

Plug this into equation

$2x + 90 + 3x = 180$

$5x + 90 = 180$

$5x = 90$

$x = 18$

Plug 18 into 2x

$2(18) = 36$
