Answer 1

The answer is can not be determined

Answer 2

Answer:

150

Step-by-step explanation:

angle R is 90 degrees ( angle sorry subtended by a diameter)

so P + Q = 180-90 = 90

as Q is twice of P ,

2P + P = 90

3P = 90

P= 90/3=30 degrees

therefore supplimentry angle of 30 degrees is 180 - 30= 150 degrees
