Question

Two angles of a quadrilateral measure 315° and 20°. The other two angles are in a ratio of 2:3. What are the measures of those two angles?

Answer 1

The measures of the two angles are 10° and 15°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360°

Subtract the given angles, 315° and 20°

The reminder is 25°

2/5 of 25 is 10.

3/5 of 25 is 15
