Question

Q-3
In the given figure PQ and MN interest at O
1. Determine Y when X=60
2. Determine X when Y=40

Answer 1

Step-by-step explanation:

Given=rayPQ and rayMN interest at O

To find=angle X and Y

solution =from the given figure

we know that,

2x+y=180 [1]

according to given x=60

2(60)+y=180

120+y=180

y=60

according to second condition

y=40

given eq

2x+y=180

2x+40=180

2x=140

x=140÷2

×= 70

Answer 2

Answer:

1.Y=60, 2.X=70 this will be answers
