Question

40) The angles of a triangle are in the ratio 1:2:3. Find the angles?
1. 15, 45, 75
2. 30, 60, 90
3. 25, 55, 105
4. 30, 70, 80​

Answer 1

Answer:

30,60,90 is the answer

Answer 2

Step-by-step explanation:

Let the angles of a triangle are x,2x and 3x.

Now, sum of all the angles of a triangle is 180°.

So, A+B+C =180°

x+2x+3x = 180°

6x = 180°

x =30°

and,2x = 60°

and,3x = 90°

so, the answer is is (2) option
