Question

the measures of the angle of a triangle are in the ratio1:2:3 find. the angles​

Answer 1

Step-by-step explanation:

let angles be 1x,2x and3x

Area of triangle = 180°

1x +2x +3x = 180°

6x =180

x= 180/6 =30

1x = 1×30=30°

2x = 2×30 =60°

3x = 3×30 = 90°

Answer 2

Answer:

Here,

Let the angles of the triangles be 1x, 2x and 3x respectively.

1x+2x+3x - 180⁰( the sum of angle of a triangle is 180⁰)

or, 6x - 180⁰

or, x - 180/6

x - 30⁰

Then,

1x - 1*30⁰ - 30⁰

2x - 2*30⁰ - 60⁰

3x - 3*30⁰ - 90⁰

Step-by-step explanation:

just use the property of triangle
