Question

6. One angle of a triangle is 80° and the other two are in the ratio 1 : 3. Find these angles.

Answer 1

Step-by-step explanation:

we know that,

sum of all angles of triangle area s 180°

so,

one angle =80°

let other two angles bs x and 3x.

80+x+2x=180.

80+3x=180

3x=180-80

x=100/3

x=33.3

and

3x=33.3*3

3x=99.9

Answer 2

Answer:

The other 2 angles will be 25 and 75 degree

Step-by-step explanation:

Let the 2 angles be x and 3x

For x as a real number

x+3x+80=180(angle sum property)

4x+80=180

4x=180-80

4x=100

x=100/4

x=25

The other angle will be 3*25=75
