All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°

102+39=141°
180-141=39°
x = 39°

When you add up all the angles it should equal to 180 so 180-102=78 then 78-39=39 so x=39

What’s the answer to 3x/x+5+7/x+5

uranmaximum [27]

Ambiguous expression. I think you meant:
3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
x+5

There's no "answer." All you can do here is to combine the terms and simpify the resulting sum.
