Answer:
x = 60°
Step-by-step explanation:
Given that it is a right triangle, then it means that one of its angles has a measure of 90°. And since we have another angle with a measure of 30°, then we can add these two measures and subtract from 180° (because the sum of the measures of all the angles within a triangle is 180°).
Therefore:
x = 180° - 90° - 30°
x = 60°
