Question

Q5. The angles of a triangle
are in the ratio of 5:3:7. The
largest angle of the triangle is​

Answer 1

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

5x+3x+7x=180 (angle sum property)

15x=180

x=12

The largest angle is clearly 7x=7×12=84

Answer 2

Answer:

84

Step-by-step explanation:

angles in a triangle add up to 180

5 + 3 + 7 = 15

180/15 = 12

12 x 7 = 84
