Question

If one angle of a triangle is 60digri and the other two angles are in the ratio 1:2,find the angles????

Answer 1

Answer:

40 and 80

Step-by-step explanation:

let the two angles be x and 2x

now,

x+2x+60=180

3x=180-60

x=40

therefore the two angles are 40 and 80 degree respectively

Answer 2

Let, the other two angles be x and 2x.

Given one angle = 60°

As we know that,

$<b>Sum of all angles of triangle = 180°</b>$

So,

x + 2x + 60° = 180°

3x + 60° = 180°

3x = 180° - 60°

3x = 120°

x = 120° / 3

x = 40°

One angle = x = $<b><u>40°</b></u>$

Another angle = 2x = 2 ( 40° ) = $<b><u>80°</b><u>$
