Question

7. If one angle of a triangle is 60° and the other two angles are in the ratio 1 : 2, find the angle
​

Answer 1

Step-by-step explanation:

Given ratio = 1:2

sum of ratio = 1 + 2 = 3

first part = 1/3*60 = 20

second part = 2/3*60 =40

Answer 2

Answer:

40° and 80°

Step-by-step explanation:

Let one of the other two angles be x.

Therefore, the second one will be 2x.

Sum of all the three angles of a triangle is equal to 180°.

60° + x + 2x = 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°.
