Question

If a triangle has a right angle and a 30 degree angle, what is the measure of the third angle?

Answer 1

I think the answer is 60 I’m not sure but good luck

Answer 2

Answer:

60

Step-by-step explanation:

All triangles have a total measurement of 180 degrees. So to find the last angle measure subtract 90 and 30 from 180, 180-(90+30). This equals 60 degrees. Additionally, a triangle with a 90 and 30 degree angle is known as a 30-60-90 special right triangle. All of these triangles will have 60 as their third measurement.
