Question

Please give the solution for above equation

Answer 1

sorry I cannot give you solution

Answer 2

Answer:

C. 36°

Step-by-step explanation:

The illustration shows two secants intersecting in the interior of a circle, therefore the measure of the angle formed is one-half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

Given:

Intercepted arc is arc AC which measures 30°

Arc intercepted by the vertical angle is arc DB which measures 42°

Asked: What is the measure of ∠AEC?

Solution:

measure of  ∠AEC = 1/2 (measure of arc AC + measure of arc DB)

                m ∠AEC = 1/2 ( 30° + 42° )

                  m ∠AEC = 1/2 ( 72° )            get the half of 72°

                   m ∠AEC = 36°
