Question

In a right angled triangle two acute angles are in the ratio of 4:5. Find the acute angles of the triangle.

Answer 1

Answer:

In right angled triangle one angle will be 90°.

let the acute angles be 4x and 5x.

So,4x+5x+90°=180°

9x=90°

x=10°

So,the acute angle are 40° and 50°.

Answer 2

Answer:

Vertical angles are two nonadjacent angles formed by two intersecting lines. You can use the corner of a piece of paper to see that ∠ZVY and ∠WVU are less than right angles. Therefore, and are acute vertical angles. ... two obtuse adjacent angles angles
