Answer 1

Answer:

angle B = 70°

angle D=85°

Answer 2

Answer:

angle B=55°

angle D=70°

Step-by-step explanation:

Using angle sum property

QCB + CQB + CBQ = 180°

85° + 40° + CBQ = 180°

125° + CBQ = 180°

CBQ = 180° - 125°

CBQ = 55°

THEREFORE angle B = 55°

_____________________________________

CQB = AQD [vertically opposite angles]

thus, AQD = 40°

Now using ANGLE SUM PROPERTY

AQD + QAD + QDA = 180°

40° + 70° + QDA = 180°

110° + QDA = 180°

QDA = 180° - 110°

QDA = 70°

THEREFORE angle D = 70°
