and here is the hint
OpenStudy (anonymous):
and this answer is mixed number
OpenStudy (anonymous):
It looks like you will need a system of equations.
x^2+h^2 = 20^2
y^2+h^2 = 48^2
x+y=52
OpenStudy (anonymous):
y^2-x^2= 1904
and x = 52-y

law of cosines formated for a side will give you the angles; then sin them :)
OpenStudy (anonymous):
if you substitute 52-y in for x you should be able to solve to y and then x, and finally h.
(although you could use sin and cos as well if you know how to use them)
OpenStudy (anonymous):
can u show me in the easy way before i will get confuse
OpenStudy (anonymous):
I need to go now because i have my next class now bye
OpenStudy (amistre64):
the hint looks to be congruent sides of congruent tris

OpenStudy (amistre64):
h/48 = 20/52
h = 48(20)/52
OpenStudy (amistre64):
y/48 = 48/52
y = 48(48)/52
OpenStudy (dumbcow):
you guys are correct but there is an easier way using ratios
yeah what amistre is saying
