Ответ:
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°
