Question

pls find ans. for this...

Answer 1

Answer:

x + 30 = 180 ( linear pair )

x = 180 - 30

x = 150

y= 90 +30 (exterior angle property)

y = 120

z + 90 = 180 ( linear pair )

z = 90

Answer 2

Step-by-step explanation:

Sum of angles of triangle is 180°

so

adding angle we get

90°+30°+A°=180°

120°+A°=180°

A°=180°-120°

A°=60°

now all angles are supplymentary

so

x+90°=180°

x=90°

y+A°=180°

y=180°-A°

=180°-60°

=120°

now

z+30°=180°

z=150°
