the base angles A and B of a Trapezium ABCD measure 110 degree 120 degree find the angles c and d​ explanation need ​

Answer 1

Step-by-step explanation:

<A = 110°

<B = 120°

let <C = X

let < D = X+1

A.T.Q. ( According to question )

<A+<B+<C+<D= 360°

110°+120°+X+X+1= 360°

231°+2X=360°

2X=360°-231°

2X=129°

X=129°÷2

X=64.5

X+1=65.5

Check

110+120+64.5+65.5=360

360=360
