If you have:
tan of 25=x over 250
How do you find x?
Also, if u have
sin of x= 8 over 13 how do you find x??
PLEASE HELP

The inverse functions of sin is arcsin (sin^-1).
tan (25) = x/250 can be solved by evaluating tan(25) * 250 = x,
for sin(x) = 8/13 simply use the inverse function of sin: x = arcsin(8/13)

tan of 25=x over 250
x= 250* tan25 = 250(.4663) = 116.577
sin x= 8/13
x = arcsin (8/13) = 37.98 degrees

for the first one: tan(25)=x/250
you just have to multiply by 250
but for the second one you have to use the arcsin function on your graphing calculator.
Cake.

x is 250 divided tan to the power of 3.14. then divide the answer by 5 The answer is 1.324
hang on....ah no its 1.432, I accidentally counted the wrong finger on my hand.

im so sorry. i have no idea. i just started trig, errghh i hate it!
the first one makes sense for x=10
but honestly i have no idea what you would do, or if that even makes sense... sorry
