Question

The two angles of a triangle are equal and the third angle measure is 700

. Find the measure of

equal angle​

Answer 1

Answer:

let the angle be x

x+x+70°=180°(sum of all angles of triangle is 180°)

2x=180-70

x=110/2

x=55°

Answer 2

Answer:

Sol:

Third angle = 700 (given)

Let the two angles be 'x'

By angle some property of a triangle

x+x+700=180

2x+700 =180

2x=700-180=520

2x=520

x=520 divide 2 = 260

Therefore, 2x=260

So, angle first= 260

angle second=260

I think you want to write '70' but by mistake you have written '700'.

If you want to write '70' so here is your answer:

Let the two angles be 'x'

By angle some property of a triangle

x+x+70=180

2x+70=180

2x=180-70=110

Therefore, angle first= 2 divide 110= 55

second angle=2 divide 110= 55
