Question

????????????????????????​

Answer 1

Step-by-step explanation:

Sum of angles of a triangle =180

angle a=5x

angle b=6x

angle c=7x

a+b+c=180

5x+6x+7x=180

18x=180

x=180/18

x=10

a=5*10=50

b=6*10=60

c=7*10=70

Answer 2

Answer:

let's the angles be 5x , 6x , 7x

using angle sum property of triangle

5x + 6x + 7x = 180⁰

18x = 180⁰

x = 180⁰/18

x = 10⁰

thus, the angles be 5×10= 50 cm

6×10 = 60 cm

7 ×10 = 70 cm
