Question

this is the questions

Answer 1

Answer:

1) angle D=3x+50°

angle B=80°

the sum of all angles in a quadrilateral is 360.

3x+50°+80°=180°

3x=180-130

x=50/3

x=16.66

here we taken sum of two angles only kk na u understand that

2) angle A=90°[since, the right angle=90°]

angle B=x

angle C=56°

angle D=x

sum of all angles=360°

90°+x+56°+x=360°

2x+146°=360°

2x=360-146

x=214/2

x=107°
