Question

in the given figure, if PQ is a line , then find the value of x​

Answer 1

Step-by-step explanation:

since, angle PQ = 180

therefore, 180= 30+7x+3x or 30+3x+7x=180

=> 7x+3x=180-30

= 150

=>10x=150

=>x=150/10

=15

therefore,. x= 15

Answer 2

Answer:

PQ is a straight line it means its measure is 180°

Sum of all the angles on a straight line is 180°

So,

=>30°+ 7x + 3x = 180°

=>30° + 10x = 180°

=>10x = 180°– 30°

=>10x = 150°

=>x = 150°/10

Ans x = 15°
