Question

The sum of three angles of a triangle is 80° and the difference is 20°, find three angles​

Answer 1

$\huge \bf \ \: question$

the sum of three angle of a triangle is 80 degree and the difference is 20 degree find three angles ?

answer :-

let the two angles be "x" and "y" .

Then , according to the given question

x+y = 80

x-y= 20

so, 2x=100

x=100/2

x= 50

then y =80-50=30

Now, the Third angle is =180-80=100° .

Hence , the all three angles of the triangle are 50°,30°,100°
