Question

What is the sum of the measures of the interior angles at vertex I and vertex J?
(1 point)
O 38°
0 52°
O 142°
O 128°

angle h is 142

Answer 1

The sum of the measures of the interior angles at vertex I and vertex J can be found by subtracting the measure of angle h from 180 degrees, since the angles at a vertex of a triangle add up to 180 degrees.

So, the sum of these interior angles is 180° - 142° = 38°.

Therefore, the correct answer is 38°.
