b. cos136°=5/x
c. sin5°=26/x
d sin x=5/12
e. cos x=2/15
i need help.
You're going to need a calculator for four of these. The first is elementary:
For b and c: rearrange the equation.
For example,
Then it's plug and chug.
d and e are similar.
For d:
You have no choice but to use the calculator on both of these. Note that is the inverse sine function.
