Question

16. In Figure 6, what value of y will make POQ a straight line?​

Answer 1

Answer

For POQ, to be a straight line, it's necessary that the sum of both the angles is 180°. Thus;

2y - 25 + 3y + 5 = 180

=> 5y - 20 = 180

=> 5y = 200

=> y = 40°

Answer 2

Answer:

y = 40

Step-by-step explanation:

2y-25 + 3y + 5 = 180 ...........LPoA

5y - 20= 180

5y = 200

y = 40
