Question

given llgram ABCD , angleD=70degree find all angles.​

Answer 1

i hope its clear to you..

plss brainliest my answer..

Answer 2

If; angle D = 70°

So; angle B=70°

(because opp. angles of a ||gm are equal)

Let Angle A=C=x

we know that sum of the angles of a ||gm id 360°.

So;

$angle \: a + b + c + d = 360$

$x + x + 70 + 70 = 360$

$2x + 140 = 360$

$2x = 360 - 140$

$x = \frac{220}{2}$

$x = 110$

So; Angle A=C=110°

HOPE IT HELPED YOU☺
