Answer:
y = 24 - 2x / 5
Step-by-step explanation:
I assume it is a triangle since there is 3 angles.
Triangle's three angles add up to 180 degrees.
So,
> 50 + 2x + 5y + 10 = 180
> 60 + 2x + 5y = 180
We will subtract 60 from both sides, to get rid of 60 in the left side.
> 2x + 5y = 120
To isolate 5y, we will subtract 2x from both sides.
> 5y = 120 - 2x
To isolate y further, we will divide by 5 from both sides.
> y = 120 / 5 - 2x / 5
> y = 24 - 2x / 5
I hope it will be understood.
If I have any inaccuracies please let me know.
Have a nice day and never stop questioning!
