Answer:
79
Step-by-step explanation:
<7=4x+1(corresponding angles)
So
3x+4+<7=180(angles on straight line)
So
3x+4+4x+1=180
7x+5=180
7x=180-5
7x=175
x=25
Now
<8=3x+4 (vertical angles)
So.
<8=3(25)+4
=75+4
=79
Answer:
A) ∠BEC is one-half of ∠BAC
B) ∠BEC = 60°
C) ∠BDC = 120°
Step-by-step explanation:
C) arc BDC = 120°
arc BEC = 360° - 120° = 240°
∠BDC = 1/2(240°) = 120°
