Question

Two angle measures in a scalene triangle are 77° and 62°. what is the measure of the third angle

Answer 1

For any triangle, the three angles must add up to 180 degrees. So if you have two of the angles and want to find the third, make an equation, designating the unknown angle, x, to find the sum. It should look like this: $77+62+x=180$. Now isolate the x-variable and you find the third angle to be 41 degrees
