Question

please help me please​

Answer 1

Answer:

x = 16

Step-by-step explanation:

(2x + 60 deg) + (3x - 40deg) = 180 deg

(since POQ is 180 deg)

2x + 60 + 3x - 40 = 180

5x + 100 = 180

5x = 80

x = 16

sorry, I was not able to help you out with the second one...

thanks!

Answer 2

Hello

2.(a).

POQ is a straight line

⇒<POR + <ROQ = 180°

⇒ 2x + 60° + 3x - 40° = 180°

⇒ 5x = 180° - 20° = 150°

⇒ x = 30°

2.(b).

NOT CLEAR

2,(c).

Supplement of 79° = 180° - 79° = 101°
