Question

In Quadrilaterals ABCD, Angel A+angelB=150° , angelC+Angel D =?​

Answer 1

Answer:

210

Step-by-step explanation:

the sum of all angles in a triangle is 360 degree so 360-150=210..

Answer 2

Answer:

Angle C+D= 210 degree

Step-by-step explanation:

We know

All four angles of a Quadriletaral = 360 degree

Here,

Angle A+B is given 150 degree

So,

A+B+C+D= 360

Or, 150+C+D=360

Or, C+D=360-150

Or, C+D=210

Therefore, C+D= 210 Degrees (Proved)
