Final answer:
To find the missing angle measure of a triangle, subtract the given angles from 180.
Step-by-step explanation:
To find the missing angle measure of a triangle, you can use the fact that the sum of the angles in a triangle is always 180 degrees. So, 90 + 36 + x = 180, where x represents the missing angle. To solve for x, subtract the given angles from 180: x = 180 - 90 - 36 = 54 degrees. Therefore, the missing angle measure is 54 degrees.
