Question 16 Properties of Triangle Exercise 15.2
Next
Answer:
Given that one of the angles of the given triangle is 60.
Also given that the other two angles of the triangle are in the ratio 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
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.
