Question

If mBCD = 148°, what is m∠BCD?

74°
32°
148°
106°

Answer 1

Option (1)

Explanation:

Given : m(arc BCD) = 148°

By the property,

Inscribed angle formed by an arc measures half the measure of the arc.

m(arc BCD) = 2(m∠BCD)

148° == 2(m∠BCD)

m(∠BCD) = 74°

Therefore, Option (1) will be the correct option.
