Question

HELP ASAP PLEASE!!
8.What is mZDFE?

Answer 1

119

Explanation:

mCE + mBD + mBC + mDE = 360

84 + 38 + mBC + m DE = 360

mBC + mDE = 360 - 84 - 38 = 238

Angle DFE is an interior angle in the circle therefore

DFE = (mBC + mDE)/2 = 238 / 2 = 119

Answer 2

• 119°

Explanation:

According to diagram:

• m∠DFE = m∠BFC (vertical angles)

Angle formed by two chords is half the sum of the intercepted arcs:

• m∠DFE =
• 1/2(mBC + mDE) =
• 1/2(360 - mCE - mBD) =
• 1/2(360 - 84 - 38) =
• 1/2(238) =
• 119
