Question

The measure of one interior angle of a triangle is 45°. What can you conclude about the other two interior angles of the triangle?

One of the other angles must be a right angle.
The sum of the measures of the other two angles is 135°.
The other two angles must be acute angles.
One of the other angles must have a measure greater than 90°.

Answer 1

The sum of the measures of the other two angles is 135° or b

Explanation:

Answer 2

The sum of the measures of the other two angles is 135°.

Explanation:

The sum of the interior angles of a triangle will add up to 180°. So by subtracting 45° from 180°, the other two angles have to add up to 135°.
