<PRE><B>Question 51390</B>
One angle in a triangle is a right angle, and one angle is equal to 30. What is the measurement of the third angle?
--------------
Let the measure of the third angle is x.
EQUATION:
90 + 30 + x = 180 degrees
120 + x = 180
x = 60 degrees (This is the measure of the 3rd angle.)
