| In the problem statement, we are given two angles of a triangle. They are equal to 35 ° and 100 °.

The sum of all the angles of any triangle is 180 °. So, knowing the two angles of the triangle, we can find the third. It is necessary to subtract from 180 ° the sum of the two known angles of the triangle:

180 ° – (35 ° + 100 °) = 45 °.

Answer: the angle of 1 triangle is 45 °.
