    is there a relation between the two lower triangle? in particular, is there a relation between 2x+3.5 and 3x+1.5?

    It doesn't look like AC depends at all on the bottom half of the triangle...

    Prove PAC and BAP are congruent triangles. Then you can figure out what AC is.

    they have 2 sides that are congruent right?

    yes, BP is congruent to CP, and the vertical side AP is congruent with itself

    Ah okay. So side BP and PC are congruent because it is given by the marks. and angle BPA and CPA are right angles therefore they are also congruent . AP is congruent to AP because of the reflexsive property. Therefore triangle APB is congruent to triangle APC. Therefore AB is congruent to AC. AC= 15

    yes, @Chocolatechocolatechip is correct. You don't actually have to prove it for this triangle, but that reasoning is correct. AC corresponds to AB, and since the 2 triangles are congruent, AC must be congruent to AB, so AC = 15.

    @Chocolatechocolatechip what do I do to find DB? do i put the 2 equations equal to each other?

    Do the same thing, prove the two smaller triangles are congruent. They are congruent by Side-angle-side. Therefore the sides BD and CD are equal. Therefore 2x + 3.5 = 3x + 1.5. find x and then input x back into the equation to find BD

    x= 2. Then put 2 into the equation. so it would be 2(2) + 3.5
