Question

Q3. In the given figure, what value of x will make AOB a line?

Please answer my question as soon as possible because it is very important for me ​

Answer 1

Answer:

2x + 30 + 3x = 180⁰ (Linear pair)

5x + 30 = 180⁰

5x = 150⁰

x = 30⁰

Answer 2

Step-by-step explanation:

2x+3x+30=180 (l.p.)

5x+30=180

5x=180-30

5x=150

x=150/5

x=30

AOP=2×30+30

=60+30

=90

POB=3×30

=90
