Question

Find the value of x in the given figure ....pls answer it fast...

Answer 1

150°+3x+4x=360°(complete angle)
Therefore, 7x=360°-150°
X=210/7
Therefore x= 30
Now, 4x=4×30=120°
And 3x=3×30=90°

Answer 2

150+4x+3x=360 (sum of all angles)
150+7x=360
7x=360-150
7x=210
x=210/7
x=30

Now substituting the value of x

4x=4(30)
=120

3x=3(20)
=60

Hence we have found all the angles

Hope it helps......:)
