Question

A circle is centered on point BBB. Points AAA, CCC and DDD lie on its circumference. If \orange{\angle ADC}∠ADCstart color #ffa500, angle, A, D, C, end color #ffa500 measures 61^\circ61 ∘ 61, degrees, what does \blue{\angle ABC}∠ABCstart color #6495ed, angle, A, B, C, end color #6495ed measure?

Answer 1

the real answer is 124,

Explanation:

maybe stop complaining and put the correct answer yourself so others like me dont have to suffer.

Answer 2

122°

Explanation:

The measure of the central angle is twice the measure of the inscribed angle that subtends the same arc.

∠ABC = 2×∠ADC = 2×61°

∠ABC = 122°
