Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)

Step-by-step explanation:
ok so first you eat my poop then you eat your own poop and then you eat my dog poop
To find the area of this rectangle you multiply the length by the width, like so (x+2) x (2x+5) .
To find the perimeter of this rectangle you add all the sides using this equation,
(x+2)+(x+2)+(2x+5)+(2x+5) .
165
5x5= 25
12x12=144
25+144= 165
