Question

The sum of the measures of the angles of a quadrilateral is 360°. For the figures given below, write and solve an equation to find the value of x.
pls solve it in notebook it's urgent pls answer it it's two sums pls answer it i beg u​

Answer 1

Since , sum of all angles of a quadrilateral is 360°

so , 109°+96°+70°+x = 360°

= x = 360° - 275°

so x = 85°

In b.)

Similarly,

sum of all angles of a quadrilateral is 360°

so , 45°+105°+85°+x = 360°

= x = 360° - 235°

so x = 125°
