If m∠CED = 56° and m∠AEB = (7x – 8)° then what is m∠BEC?
fredd [130]

Using the definition of angles on a straight line, the measure of angle BEC is: 62°.

<h3>What are Angles on a Straight Line?</h3>

Angles that lie on a straight line add up to 180 degrees.

Thus, given that EB bisects ∠AEC, therefore:

m∠BEC = 1/2(180 - m∠CED)

Plug in the values

m∠BEC = 1/2(180 - 56)

m∠BEC = 1/2(124)

m∠BEC = 62°

Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.
