Question

If a triangle has an angle of 45° and an angle of 100°, what is the third angle?

Answer 1

35 degrees

Explanation:

The sum of a triangle is 180 degrees, so add 100 +45, and you get 145

Then you subtract 180-145 and you get 35 degrees

Answer 2

35 degrees

Explanation:

The sum of the angles of a triangle add to 180

45+100 +x = 180

145 +x =180

x = 180-145

x = 35
