The three inside angles of a triangle need to equal 180 degrees.
In a right triangle one of the angles is 90 degrees.
This means the other two angles need to equal 180-90 90 degrees.
You are given one of the angles of 52 degrees, so subtract that from 90 to find the third angle.
90 - 52 = 38 degrees.
The answer is A.
Answer:
147
Step-by-step explanation:
360-35-78-100 = 147
We just need to subtract all the angles that we were given, giving us 147.
edit: 360 is all the angles in the pie chart added up.
