Question

8.If the angles of a triangle are in the ratio 3:4:5 , then the largest angle of the

triangle measures is:

(a) 15 (b) 45 (c) 75 (d) 120​

Answer 1

Answer:

HELLO

Step-by-step explanation:

Here the largest in ratio is 5 so we can write that 5x is the largest angle. Thus the largest angle is 75°.

Answer 2

Answer:

Here is the answer =>

Step-by-step explanation:

Ratio=3:4:5

So let the angles b ‘x.’

So 3x+4x+5x=180° (Angle sum property).

12x=180°

=180/12

=15°

So x=15°

Largest angle=5x

=5*15

=75°

Hence the largest angle of the Δ is c) 75° which is the required answer.
