4. The angles of a triangle are in the ratio 3:2 : 1. Find the angles.​

Answer 1

Answer:

Rs. 75:100:125

Step-by-step explanation:

ratio 3+4+5 = 12

3000÷12=25

25x3=75

25x4=100

25x5=125

Answer 2

Question :

The angles of a triangle are in the ratio 3 : 2 : 1. Find the angles.

Solution :

Step-by-step explanation :

Let the 1st angle i.e. angleA = 3x

the 2nd angle i.e. angleB = 2x

the 3rd angle i.e. angleC = 1x

As we know, the sum of Angles of a triangle is equal to 180°

Now :

angleA + angleB + angleC = 180°

3x + 2x + 1x = 180°

6x = 180°

$x = \frac{180}{6}$

x = 30°

So, angleA = 3 × (30°)

= 90°

angleB = 2 × (30°)

= 60°

angleC = 1 × (30°)

= 30°
