∠cbe and ∠deb are same-side interior angles.

i took the test

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
