Question

prove that the sum of all angles of a triangle is 180°. Also find the angle of a triangle if they are in the ratio 5:6:7.​

Answer 1

Answer:

Answer is here =

Step-by-step explanation:

Let the angles is x

by angle sum property

5x+6x+7x = 180°

18x = 180°

x = 180°÷18

x = 10°

since x =10°

5x = 50°

6x = 60°

7x = 70°

when we add all the angles

50°+60°+70° = 180°

Hence proved!
