Can anyone help with this? There is a Picture Attached
here are the answer choices Choose one answer. a. 7.5 b. 22.5 c. 15 d. Cannot be determined
what is the actual question?
what r we supposed to do?
From the information given in the figure, what is AC?
is there more information or just what's on the picture?
just wats in the picture
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.
I don't know how to do those things its my first time learning this on online school i need steps
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.
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?
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
ohk i will let u kno what i get
okay. =)
i got 2 @Chocolatechocolatechip
x= 2. Then put 2 into the equation. so it would be 2(2) + 3.5
