Question

1) Two angles of a triangle have measures of 30 degrees and 45 degrees. What is
the measure of the remaining angle?

Answer 1

the angle sum in a triangle is 180

30 + 45 = 75

180 - 75 = 105.

The remaining angle measure is 105°.

Answer 2

Answer:

30+40+ x =180

70+x=180

x=110

Therefore the third angle is 110
