Question

the angles of triangles are in the ratio of 5:6:7:.find the angles which is equal to its supplements.​

Answer 1

Step-by-step explanation:

we know that the sum of the angles of triangle is 180

Answer 2

Answer:

Let the angles be 5x , 6x & 7x

In ∆ ABC,

<A + <B + <C = 180 [ angle sum property ]

5x +6x +7x = 180

18 x = 180

=> x = 180/18

=> x = 10

[ so the angles are 50° , 60° & 70 °]
