Answer:
x = 30
(2x)° = 60°
x = 30°
Explanation:
The two angles combined is a right angle, and a right angle is 90°, so we can put that into this equation:
2x + x = 90 which is the same as 3x = 90 because 2x + x = 3x
3x = 90
divide both sides by 3 so you can get x by itself
3x divided by 3 = x
90 divided by 3 = 30
you get x = 30
since x = 30, 2x is the same as 2 times 30, and that is 60.
