Question

A angles of triangle are in the ratio of 3:4:5. Determine the three angle

Answer 1

Answer:

let the angle be x

3x+4x+5x=180

12x=180

x=180/12

x=15

3x=45

4x=60

5x=75

Answer 2

Let the angles of the
A=3x
B=4x
C=5x

We know that
The sun of the interior three angles of a triangle is180^•

So,

A+B+C=180
3x+4x+5x=180
12x=180
x=180/12
x=15

So the angles of the triangles are
A=3x=3*15=45
B=4x=4*15=60
C=5x=5*15=75
