| If one angle of the triangle is 40 degrees, and the second is 1.5 times more, then we find how many degrees the second angle is.

You need to multiply 40 ° by 1.5.

40 ° * 1, 5 = 60 ° (gr.) – 2nd angle.

Find the sum of the degrees of two angles.

40 ° + 60 ° = 100 ° – together the first and second corners.

The sum of all sides of the triangle must be equal to 180 °.

Let’s find what the third angle of the triangle is equal to.

It must be subtracted from 180 ° 100 °.

180 ° – 100 ° = 80 ° – equals the third angle.

Answer: The third corner of the triangle is 80 degrees.
