Find the unknown angle of a triangle if 2 other angles are equal 1) 50 and 36 2) 40 and 75 3) 60 and 80 4) 25 and 120.

It is necessary to find the unknown angle of the triangle when the other two are known and their angles are 1) 50 ° and 36 ° 2) 40 ° and 75 ° 3) 60 ° and 80 ° 4) 25 ° and 120 °. It is known from geometry that the sum of all angles in a triangle is 180 °. Then, to find the third angle, you need to subtract two other angles from 180 °.

180 ° – 50 ° – 36 ° = 95 °.

180 ° – 40 ° – 75 ° = 65 °.

180 ° – 60 ° – 80 ° = 40 °.

180 ° – 25 ° – 120 ° = 35 °.
