Question

The angles of a triangle are arranged in ascending order or magnitude.ifthe difference between two consecutive angles is 10 ,find the three angles

​

Answer 1

Answer:

50°,60°&70°

Step-by-step explanation:

let the angle of one side be x°

so smaller angle will become x-10

and larger angle becomes x+10

we know that sum of interior angle is 180°

so 3x=180°

x=60°

x-10=50°

x+10=70°

Answer 2

Answer:

The three angles of the triangle are:

x, x+10, x+20.

Their sum = 3x+30 = 180, or

3x=180–30 = 150, or

x = 50

So the three angles are 50 deg, 60 deg and 70 deg.

The ratio of the angles is thus 5:6:7.

The ratio of the three sides is thus 1:(si60/sin 50) : (sin 70/sin 50)
