Question

one angle of a triangle measures 60 degree and the other two angle are in the ratio 2:1. find these angles.. ​

Answer 1

Step-by-step explanation:

Therefore, the second one will be 2x. We know that the sum of all the three angles of a triangle is equal to 180°. Hence, we can conclude that the required angles are 40° and 80°.

Answer 2

Answer:

Let the other two angles be x

we know that the sum of three angles of a triangle is 180 then

60°+ 2x + 1x = 180°

60°+ 3x = 180°

3x= 180°- 60°

3x = 120°

x = 120/3

x= 40

first angle =2x = 2 × 40 = 80°

second angle = 1x = 1× 40= 40°
