Hey , your answer is : -

Q.no. 1

5x + 20 °+ 3x - 8° = 180° (Sum of adjacent angles = 180°)

8x + 12° = 180°

8x = 168

x = 168/ 8

x = 21

5x + 20 = 125°

3x - 8 = 55°

Opposite angles of rhombus are equal .

So , <A = 125°

<B = 55°

<C = 125°

< D = 55°

Now,

Q.no. 2.

.

.

<C + < D= 180°

z + 130° = 180°

z = 50°

Now,

<y = < z ......(Alternate interior angle )

<y = 50°

Now ,

<y + < z = 100°

Mark my answer as brainlist .
