Question

In a right-angled triangle, find the other two angles if they are in the ratio 1 : 2

Answer 1

Answer:

1st angle is 30⁰ and second angle is 60⁰

Step-by-step explanation:

let's take the 1st angle as x and 2nd angle as 2x

then we know that the right angle means 90⁰ .

then the sum of all the angles is 180 ⁰.

so the equation:-

x +2x + 90⁰ = 180⁰

3x =180⁰ - 90 ⁰

x = 30 ⁰

so 2x = 2 × 30 = 60

Answer 2

Answer:

let the angles in ratio be 1x and 2x

sum of all angles of a triangle is 180°

therefore

1x + 2x + 90° = 180°

3x + 90° = 180°

3x = 180°- 90°

3x = 90°

x = 90°/3

x = 30°

therefore 1x is 30°

and 2x is 2×30 = 60°

Soo others 2 angles are 30° and 60°

hope this helps
