Fill in the Blanks
An angle is bisected, forming two new angles. Each new angle has a measure of 15°. What was the measure of the original angle? (enter number only)
Type answer...
6
Solution:
Each new angle measures 15°. Multiply by 2 to find the original, larger angle.
15° × 2 = 30°
So, the original angle measured 30°.
