Question

In a right angle triangle measure of one of the acute angle is x and of
another acute angle is y then which of the given equations express the
correct relation between both the angles?
x - y = 180°
x + y = 180°
x - y = 90°
x + y = 90°
​

Answer 1

Answer:

x+y = 90 degree

because the sum of both the acute angle is equal to right angle i.e 90 degree

Answer 2

Therefore X + Y = 90°
