Question

in a quadrilateral ABCD, angle= 100°,angle B=80°, angle D=75° then find angle C.​

Answer 1

Answer:

C=105

Step-by-step explanation:

in a quadrilateral sum of all angles is 360°

so

A° +B° +C°+ D°=360°

given A= 100°

B= 80°

C= ?

D= 75°

therefore

100°+75°+ 80+C =360

C = 360- 255

C=105°

Answer 2

Step-by-step explanation:

c=150

100+75+80+c=360

c=360-255

c=150
