Calculating lengths of triangle sides (Pythagorean)

Missing Angles in Triangles Knowing that a triangle contains 180° makes calculating the measure of a missing angle much simpler. Let's take a look at some examples. Example #1: Determine the measure of angle x. Step 1: Add

Missing Angles in Triangles

From exterior angle we can find interior angle by subtraction the exterior angle from 180 o. Interior angle = 180 o – 130 o = 50 o. Now we have two angle we can find third

Really helps with homework,and I love that it explains the steps to you. But, it's a very good app, covers basic maths such as BIDMAS through to differentiation, functions, imaginary numbers etc.
