Answer 1

Answer:

sum =180

Step-by-step explanation:

equate and put u will getjsnznzndhs. if the other day, but the fact is, but it would like the way. if the other side. the first one is the most important thing to say

Answer 2

Answer:

ABCD is a parallelogram , therefore :-

Angle A = angle C. ………..(1) , and angle A + angle B = 180°. …… …………(2)

.or, 3x+15 = 2x+35.

or, x = 20°.

From eqn. (2).

3x+15 +2y+5 = 180°. , putting x =20°.

or, 60°+15°+5°+2y = 180°.

or, 2y = 180°- 80°.

or, 2y = 100°. => y = 100°/2 = 50°.

Thus , x = 20° , y = 50°. Answer.
