Question

In a right angled triangle, the acute angles are in the ratio of 4:5 . The difference of the 2 acute angles is
20
40
50
10
​

Answer 1

Answer:

10 is the correct answer

Answer 2

Step-by-step explanation:

In a right angled triangle one angle would be 90⁰

let other two angles be 4x and 5x.

by angle sum property,

90⁰+ 4x + 5x = 180⁰

9x = 90⁰

x = 10⁰

the angles are 40⁰ and 50⁰

difference = 50⁰-40⁰ = 10⁰
