Question

If one of the traingle is 60° and the other two angle are in ratio 1:2,Find The Other Angle.​

Answer 1

Answer:

The other two angles are 40° and 80°

Step-by-step explanation:

Given that one of the angles of the given triangles is 60°

Also given that the other two angles of the triangle are in the ratio of 1:2

Let one of the other two angles be x

Therefore, the second one will be 2x

We know that the sum of all the three angles of a triangle is equal to 180°

⇒60°+x+2x=180°

⇒60°+3x=180°

⇒3x=180°-60°

⇒3x=120°

⇒x=120/3

⇒x=40°

⇒2x=2×40

⇒2x=80°

Hence, we can conclude that the required angles are "40° and 80°"
