Question

If three angle of a triangle are in the ratio of 3:4:11, find the least angle

Answer 1

Answer:

30°

Step-by-step explanation:

As the ratio is 3:4:11, let the angles are 3a, 4a and 11a.

As the sum of the angle inside triangle is 180°.

=> 3a + 4a + 11a = 180°

=> 18a = 180°

=> a = 180°/18

=> a = 10°

As the least number is 3a, least angle is 3(10°) = 30°

Answer 2

Answer:

the sum of angle is 180°

3x+4x+11x=180

18x=180

x=180/18

x=10

put value of x in 3x,4x and 8x

3x= 3×10

=30

4x= 4×10

= 40

11x= 11×10

= 110

So the least angle will be 30° or 3x

Step-by-step explanation:

if there is ratio we can write x and add them
