Question

One acute angle of a right traingle is 25degree ,then the other angle is

Answer 1

Right triangles means one angle is 90deg and second in this case is 25deg
Using Angle sum property : 180deg = 90deg + 25deg + x
So, x = 180deg - 115deg
x = 65deg

Answer 2

Answer:

Finding Angles

We know that the interior angles of a triangle add up to 180°.So,

x + y + z = 180°

It was given that, one of the angles is an acute angle, measuring 25°

25° + y + z = 180°

It was also given that, this is a Right Angled Triangle. Which means, one of the angles is 90°

25° + 90° + z = 180°

Adding Up

25° + 90° = 115°

So,

115° + z = 180°

(Transversing of 115° to RHS)

z = 180° - 115°

z = 65°

So, the other angle is an acute angle, measuring 65°
