Question

In ABCD, M angle A = 70°. m angle B = 110° and m angle c = m angle D. Find the angle C and angle D​

Answer 1

Answer:

M angle a=70°

angle a congruent angle d

......(opposite angles )

so that's why angle a=70° and angle d=70°

M angle b=110°

angle a congruent angle c

......(opposite angles )

so that's why angle b=110° and angle c=110

Answer 2

Answer:

If ABCD is quadrilateral

Then,

Sum of all angles of quadrilateral = 360 degree

A+B+C+D=360

70+110+C+D=360

180+C+D=360

C+D=360-180

C+D=180

But C=D

C+C=180

Therefore

C=180÷2

C=90 Degree
