Question

If the three angles of a triangle are in ratio 2:1:2 . find all the angles of a triangle
​

Answer 1

Answer:

2x=2×36=72°

x=36°

2x=2×36=72°

Step-by-step explanation:

sum of all angles of a triangle=180°

2x+1x+2x=180°

5x=180°

x=180°/5

x=36

2x=2×36=72°

x=36°

2x=2×36=72°

Answer 2

Answer:

2x+1x+2x= 180 degree

5x= 180 degree

x= 180/5

=36

2x= 2x36=72

1x= 36

2x= 72

therefore 3 angles are 36,72,72

check: add the 3

sum= 180 degree

therefore correct
