Question

8. From the figure, find the value of x
​

Answer 1

It’s a quadrilateral. The sum of all angles of a quadrilateral is 360.

So,
100 + 95 + 60 + x = 360
255 + x = 360
x = 360 - 255
x = 105.

Therefore, forth angle = 105.

Answer 2

$\huge\mathbb\red{Answer}$

WE KNOW THE SUM OF ANGLE OF A QUADRILATERAL IS 360°

so in this figure x°+100°+60°+95°=360°

=>x°+255°=360°

=>x°=360°-255°

=>x°=105°
