Answer:
x=23 degrees
Step-by-step explanation:
We know that the sum of interior angles in a triangle is equal to 180 degrees, and we see that one of the angles is 67 and the other one is 90 degrees. So we can do this two ways, ones more complicated then the other that you may not of learned yet
The first way:
You simply do 180-67-90 to get 23
Second way:
We can use the exterior angle theorem to know that 67+x=90 degrees so you simplify on both sides and you get 23 again.
