Answer:

34

Step-by-step explanation:

Angle A and B are complementary which means they both add up to 90 degrees. Angle A is x+22 while angle B is only x. If we add both together, we can call angle A+B to be 2x+22. We can rewrite this as 2x+22=90. Take the 22 over to the other side and its sign changes so it is now 2x=90-22. 90-22=68 so now we have 2x=68. To isolate the x divide both sides by 2 which gives us x=34.

complimentary angles mean angles that add up to 90 so you could rewrite this as x + 22 + x = 90
then you can rewrite that as
2x + 22 = 90
from here on, you use inverse operations to solve for x, subtracting 22 then dividing what’s left by 2
2x = 90 - 22
2x = 68
x=34
