Question 1015078

will someone please help my daughter because i don't understand how to do this problem it says that triangle TOP and ACE are similar what is the measure of E in triangle TOP, T is the bottom left angle O is the top of the triangle and P is the bottom right angle of the triangle in triangle ACE, A is the bottom left angle C is the top of the triangle and E is the bottom right angle what is the measure of E it says to let P=3.5, T=4.25 and A=2.125 please help her 
<pre>I already explained this in problem # 1014741:
Set up a proportion as follows, if you're looking for side e, which is the same as segment AC:
{{{4.25/2.125 = 3.5/e}}}
{{{2 = 3.5/e}}}
2e = 3.5 ------ Cross-multiplying
e, or AC = {{{3.5/2}}}, or {{{highlight_green(1.75)}}} units
