3X-39°+X+52°25'=180°

I'm assuming you want to solve this equation: 3x-39+x+52-25=180. First, let's rewrite this so we know where the negatives are, and we can just add. 3x + (-39) + x+52 + (-25) = 180. Note that x=1x. Next, we can combine like terms: that is, terms with the same coefficient. 3x and x both have x in them, so they are like terms. - 39, 52, and - 25 are also like terms because they have no coefficients. 3x+1x=4x, and - 39+52 + (-25) = 38. So, 4x-12=180. Finally, let's solve for x. 4x-12+12=180+12. 4x=192. 4x/4=192/4. x=48 degrees.

Answer: x=48 degrees
