Answer:
a. m<DAB = 36°
b. m<B = 54°
c. m<C = 74°
Step-by-step explanation:
a. m<DAB = m<CAB + m<CAD
m<DAB = 20° + 16° (substitution)
m<DAB = 36°
b. m<B = 180° - (90° + m<DAB)
m<B = 180° - (90° + 36°) (substitution)
m<B = 54°
c. m<C = 180° - (90° + m<CAD)
m<C = 180° - (90° + 16°) (substitution)
m<C = 74°
Step-by-step explanation:
In the picture above.
Number 2 I suppose that as a straight line
so , it becomes easy to solve for y angle.
I hope that it's a clear solution.
Answer:
