Question

4. The angle A of a triangle is 2/3 times the angle B and the
angle B is 3/4 times the angle C. Find the angles of the
triangle.​

Answer 1

Answer:

40° , 60° , 80°

Step-by-step explanation:

B = 3C/4

A = 2B/3

= 6C/12

= C/2

angles are C, C/2 , 3C/4

sum of angles = 180°

C + C/2 + 3C/4 = 180

4C/4 + 2C/4 + 3C/4 = 180

9C/4 = 180

C = 180 × 4/9

= 20 × 4

= 80°

B = 3C/4

= 3× 80/4

= 60°

A = C/2

= 40°

Answer 2

Answer:

ans is 40°, 60°, 80°

Step-by-step explanation:

We can also solve this problem without simplifying .

Here it is that amgle A is 2/3 times than angle B and angle B is 3/4 time the angle C . We can see that the value are growing + 1/1 { eg 2+1/3+1 i.e = to the next angle digit i.e angle B is 3/4 }. Therefore the amgles will be 40° 60° 80° { beacuse sum of all the angles of a triangle is 180° and here we can see that 40° +60° +80° =180°}

It seems to be a weird ans but its correct . And if you found any difficulty in this ans you can apply the my above method also

Hope it will help you
