^BAb=60+x+90=180 (sum of angles in a triangle)
x=180-150
x=30

^bAC=90-30=60

^bCA=90+y+60=180 (sum of angles in a triangle)
y=180-150=30

x=30
y=30

Hope the answer helps

Answer:

x=25⁰

y=25⁰

Explanation:

ABC+BAC+ACB = 180⁰

65⁰+90⁰+y = 180⁰

y = 180⁰-155⁰

y = 25⁰

In triangle ABD,

ABD+ADB+BAD = 180⁰

65⁰+90⁰+x = 180⁰

x = 180⁰-155⁰

x = 25⁰
