please help answer is (1)=x = 58, y= 48|| (2) = x=37, y=53.​

Answer 1

Answer:

(i)y=180-(50+90) (the third angle in the triangle is 90° as angle in a semicircle is 90°)

y=40°

Similarly, x=58°

(ii) x=37° (it is given that the two lines are parallel)

y= 180-(90+37)

y=53°

Answer 2

Answer:

ans is y= 53°...........
