Answer:
x = 55 degrees
Explanation:
The angles in a triangle add up to 180 degrees. We are already given 2/3 of the angles that make up the triangle.
The two given angles are 35 degrees and 90 degrees (we got the ninty from the right angle)
We can add these given angles together and subtract them by 180 to find the measure of the missing angle:
35 + 90 = 125
180 - 125 = 55 degrees
