Question

The measure of two of the interior angles of a triangle are 68° and 70°.

What is the measure of the third interior angle?

Answer 1

68 + 70 = 148
180 - 148 = 32

interior angles of triangle total 180 degrees

Answer 2

the answers are 222 42 22 and 62

Answer 3

was just a mistake in the calculation there.

the sum of angles of a triangle is 180°

so, if you add up the other two angles (68 + 70), you have 138
then subtract that from the total of 180: 180 - 138 = 42°

Answer 4

thanks altig :)
