Question

In a scalene triangle, the sum of the bigger two angles is 140 degree. The smallest angle is half the biggest angle . Find the three angles

please give a brief explaination​

Answer 1

Answer:

Well we know that the sum of the angles of any triangle equals to 180, So basically the third angle which is not mentioned in the question is 40 degrees.

( 180 degrees -140degrees of the two bigger angles= 40 degrees)

Here we know that the bigger two angles sum is 140 so basically the third angle which not mentioned in the question which I found is 40 degrees is the smallest angle!

So here the question says double the smallest angle is the biggest angle so

here we found three of the angles

The biggest one -- 80 degrees

The smallest one -- 40 degrees

And the last angle -- 60 degrees

Hope it helps

Answer 2

Answer:

The angles are 40°, 60° and 80°.

Step-by-step explanation:

Let smallest angle=x

Biggest angle=2x

Let other angle 140-2x

140°+x=180

x=40°

2x=80° and

140-2x=60°
