Answer:
x = 45°
y = 90°
Step-by-step explanation:
The 135° is on a line, so 180° - 135° = 45°
Since this is an isosceles triangle, x will be equal to 45° as well.
The sum of a triangle's angles is 180°, so if we add them all together and subtract from 180° we will get our y.
180° - (45 + 45) = y
180° - 90° = y
90° = y
(a triangle can be both an isosceles and a right-triangle!)
Have a nice day!
