is there a relation between the two lower triangle? in particular, is there a relation between 2x+3.5 and 3x+1.5?
anonymous
  • anonymous
It doesn't look like AC depends at all on the bottom half of the triangle...
anonymous
  • anonymous
Prove PAC and BAP are congruent triangles. Then you can figure out what AC is.

I don't know how to do those things its my first time learning this on online school i need steps
anonymous
  • anonymous
they have 2 sides that are congruent right?
anonymous
  • anonymous
yes, BP is congruent to CP, and the vertical side AP is congruent with itself
anonymous
  • anonymous
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
anonymous
  • anonymous
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.

omgeee u broke tht down so well and i completely understand it!! thanks so much!

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

  • anonymous
ohk i will let u kno what i get
anonymous
  • anonymous
okay. =)
anonymous
  • anonymous
i got 2 @Chocolatechocolatechip
anonymous
  • anonymous
x= 2. Then put 2 into the equation. so it would be 2(2) + 3.5
