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°
2x + y = 180°
3 x - y = 90°
X + y = 90°
​

Answer 1

Answer:

4th option

x+y=90

because sum of three angles of a triangle is equal to 180 degree and in right angled triangle one angle is equal to 90 degree,

therefore sum of other two angles becomes of 90

Answer 2

Answer = X + Y =90°
