Question

In a triangle ,the ratio of angles is 3 : 7 : 5 . Find the value of ∆BAC and ∆ABC .​

Answer 1

Answer:

Step-by-step explanation:

3x + 5X + 7X=180

15x = 180

x = 180/15

 =12 degrees.

Therefore, 3x = 36 degrees

                  5x = 60 degrees

                  7x = 84 degrees

Answer 2

Answer:

the value of angles are 36°, 84° and 60°

Step-by-step explanation:

Let the angles be 3x, 7x and 5x

So,

3x+7x+5x=180° (Angle sum property)

15x=180°

x=180°/15

x=12

Therefore,

3x=3×12=36°

7x=7×12=84°

5x=5×12=60°

Hence, the value of angles are 36°, 84° and 60°
