Answer:
Y=45 X=90
Step-by-step explanation:
B is equal to C so it would be 45. Since the whole triangle must be 180 you subtract 45 and 45 from 180 and you get 90. Another way to tell C and B are the same is the 2 little lines on the sides.
y=45°(angles opposite to equal sides are equal)
x+y+45=180(sum of the interior angles of a triangle is 180)
x+45+45=180
y+90=180
y=180-90
y=90
