Question

the ratio of interior angles of triangle is 3:5:7 then find angles ​

Answer 1

Answer:

Step-by-step explanation:

Ratio=3:5:7

Lets take the angles as 3x:5x:7x

= 3x+4x+7x=180 degree

=14x= 180 degree

Therefore

X= 180/14

Therefore x= 12.8

Angles are

3x= 3×12.8=38.4

5x= 5×12.8=64

7x= 7×12.8=89.6

Answer 2

Answer:

Sum of interior angles of a triangle is $180^\circ$

Let $3x+5x+7x=180^\circ$

⇒$15x=180^\circ$

⇒$x=12^\circ$

So, required angles of a triangle are $3 \times 12^\circ, 5 \times 12^\circ \text{ and } 7 \times 12^\circ$

= $36^\circ, 60^\circ \text{ and } 84^\circ$
