please give with proper reason. ​

Answer 1

Answer:

here is the solution of your question

Answer 2

Answer:

Z=180-30=150 (sum of exterior and interior angle is 180)

X=180-90=90(same reason)

y=120 Sum if angle of triangle is 180 degree so angle opposite to y is 60 and 180-60=120

Step-by-step explanation:

also if you are class in 9 or even lower I am giving one theorem that's Sum of Angles of 2 opposite angle of triangle is equal to exterior angle 90+30=120
