Question

Find angles in the figure ??
I will do fast I will mark as brainlist ​

Answer 1

Answer:

Let ,

A = ?

B = 60°

C = 140°

D = 90°

Sum Of Angles In Quadrilateral = 360°

A + B + C + D = 360°

A + 60° + 140° + 90° = 360°

A = 360° - 290°

A = 70°

x + A = 180° ( Linear Pair )

x = 180° - 70°

x = 110°

So , x = 110°

Answer 2

Answer:

x = 110 degree

Step-by-step explanation:

sum of all angles in a quadrilateral = 360 degree.

so, <A + <B + <C + <D = 360 degree

     90 + 140 + 60 + y = 360 degree

     90 + 200 + y = 360 degree

     290 + y = 360 degree

     y = 360 - 290 degree

     y = 70 degree

x + y = 180 degree                         ( Linear Pair)

x + 70 = 180 degree

x = 180 - 70 degree

x =110 degree
