Question

Two angles of a triangle measure 47 degree and 59 degree What is the measure of the third angle? Show the work

Answer 1

The answer is 80....they all have to add up to 180

Answer 2

If you add all of the angles of a triangle together, it will always be 180 degrees. So we can use that to find the answer.

First of all, let's add the angles we already have.

47 + 59 = 106

But we want to find the last angle. So now we subtract 106 and 180(remember to put the bigger number first).

180 - 106 = 74

The last angle of the triangle is 74 degrees.
