Question

please tell
me answer of both questions​

Answer 1

Answer:

1. 55°
2. 50°

Step-by-step explanation:

1.... => <BAC + <B = ext.<C

=> <BAC= 105°-50° = 55°..

2... <R=90°

<P=40°

<Q= (180-90-40)°= 50°..

Answer 2

Answer:

•1 Angle ACD =105°

Angle ABC = 50°

Therefore , Angle BAC = Angle ACD - Angle ABC........(by remote interior angle theorem)

=105- 50

=55°

Therefore measure of angle BAC is 55°.
