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 .
