Question

the angles of a triangle are in the ratio of 3:5:7. find each angle

Answer 1

Answer:

Use the sum of angle property of a triangle

Answer 2

Step-by-step explanation:

Let the ratios of the following be 3x,5x,7x

=> 3x,5x,7x = 180°(angle sum property of triangle)

=> 15x = 180°

=> x = 180/15

=> x = 12°

Hence x=12°

=> 3x = 3×12°

=> 36°

=> 5x = 5×12°

=> 60°

=> 7x = 7×12°

=> 84°

So, each angle measure 36°,60°,84°
