Question 32

The three angles of a triangle are in the ratio 3 : 4 : 5. Then the angles respectively are:

Solution

Ratio between angles= 3:4:5

Total parts=3+4+5=12 parts

Total angle in triangle=$$180^\circ$$

12 parts$$\rightarrow 180^\circ$$

then 1 part$$\rightarrow 15^\circ$$

\therefore Angles in the triangle are

$$15\times3=45^\circ$$
$$15\times4=60^\circ$$
$$15\times5=75^\circ$$
