Asked by anonymous

a triangle has 3 sides. 1st side is (5x+3y)°, 2nd side is (3x+20)° and 3rd side is (10y+30)°. what is the value of x and y?
Answered by Reiny
You are talking about sides but use the degree symbol ????
Which is it ?
Answered by Steve
I'll assume an equilateral triangle, in which case

5x+3y = 3x+20
5x+3y = 10y+30
or
2x+3y = 20
5x-7y = 30

now just solve for x and y

If that's not the case, maybe the mysterious and elusive anonymous can either
(a) clarify the problem
(b) work on solving it and show the progress made

i meant the interior angles are 5x+3y)°, (3x+20)° and (10y+30)°.
and i know that this all simplified is 8x + 13y + 50 = 180°
but i am unsure how to find the values of x and y using this.
