Question

11.
In a quadrilateral ABCD, ZA = (2x + 4), Z B = (2x - 13)°.
Zc = (3x + 11) and ZD = (4x - 5)'. Find the measures of the angles.​

Answer 1

Hello mate ,

(2x + 4)+ (2x - 13)°+(3x + 11)+(4x - 5)=360 degree

11x-3=360 degree

11x=360+3

x=363/11

x=33 degree

1st angle=2*33+4=70 degree

2nd angle=2*33-13=53 degree

3rd angle=3*33+11=110 degree

4th angle=4*33-5=127 degree.
