Example Question #1521 : Plane Geometry
If one angle of a right triangle is 
First we need to know that when we add up all 3 angles of a triangle, the sum will always equal 
We know another angle equals 
Our final answer is 
To check our answer we can add up the three angles to make sure we come up with a sum of 
Example Question #22 : How To Find An Angle In A Right Triangle
True or false:
False
True
True
By the 30-60-90 Triangle Theorem, the ratio of the length of the longer leg of a 30-60-90 triangle to that of the shorter leg is 
the correct ratio. This is indeed a 30-60-90 triangle, and, 
Example Question #23 : How To Find An Angle In A Right Triangle
A right triangle has side lengths of 5, 10, and 11.18 inches. One angle is 63.4 degrees. What is the measure of the other angle?
None of these.
Since this is a right triangle, simply add this right angle to the given angle and subtract from 180 degrees.
The side lengths are not relevant in this problem.
