Question

I don't understand how to do this problem, could someone please explain it to me?
1) Solve for x. Round to the nearest tenth.
cos(62 degrees)=4/x

Answer 1

cos 62 is simply a number.

Answer 2

a=b/x
xa=xb/x
xa=b
xa/a=b/a
x=b/a
or in your case
x=4/cos(62)

Answer 3

So is x=4/cos(62) the answer?

Answer 4

do you have a calculator?

Answer 5

Yes.

Answer 6

find the cos button

Answer 7

you multiply x by both sides
it candles out on the right side
then you divide by cos62
so you have x=4/cos62
just plug 4/cos 62 into you calculator

Answer 8

Found it.

Answer 9

Okay, I understand. Thank you both for the help!!
