Question

hi please answer the question number 2 I will make you as brain list

Answer 1

To find :value of x
solution: x+10+4x=180
(As QOP is a straight line so sum of angles will be supplementary)
5x+10=180
5x=180-10
5x=170
x=170÷5
x=34.
Hope it will help u

Answer 2

U must know that in the above fig. it's forming a linear pair

And we know that whenever it's a linear pair the sum of angles is 180

K let us write the above statement in mathematical words,

I mean to say

AnglePQR + AngleQOR = 180

SUBSTITUTING THE VALUES OF ANGLES,

(x + 10) + (4x) = 180

5x + 10 = 180

5x = 180 - 10

5x = 170

x = 170/5

x = 34degrees
