Question

The angles of a triangle are in the ratio A:B:C = 2:5:4 find the smallest angle

Answer 1

Answer:

A is smallest.

Step-by-step explanation:

let angles be 2x 5x 4x so,

2x + 5x + 4x = 180(angle sum property)

11x = 180

x = 180/11

x = 16.36

2x =32.72

5x =81.8

4x = 65.44

hence 2x which is A is smallest angle

Answer 2

here is you answer

let ratio factor be X

so, 2=2x

5=5x

4=4x

then, 2x+5x+4x=180

11x=180

x=180/11

x=16.3( approximate)

2x=2*16.3=32.6

5x=5*16.3=81.5

4x=4*16.3=65.2

therefore, the smallest angle is 32.6. (A)
