Question

the angles of a triangle area in the ratio 3 is to 5 is to 7 the triangle is​

Answer 1

Step-by-step explanation:

3+5+7=180°

sum of all ratios =15

3/15×180=36°

5/15×180=60°

7/15×180=84°

answers are 36°,60°,84°

Answer 2

Step-by-step explanation:

Given the ratio of angles of a triangle is 3:5:7

Let the angles of a triangle be angle A, B and C

Then angle A=3x, angle B=5x and C=7x

In triangle ABC, angle A +B+C=180(since the sum of all the triangles is 180)

3x+5x+7x=180

15x =180

x=180/15=12

angleA=3x=3×12=36

angleB=5x=5×12=60

angleC=7x=7×12=84

Since, all angles are less than 90, hence the triangle is an acute angled triangle
