Problem: How do you solve cos(64)=7/x
im doing a unit in geometry on trig and the examples are easy but then the actual hw is like really hard :(
cos(64) has a real value, so you must be trying
to solve for x.
cos(64) = 7/x
x * (cos(64)) = (7/x) * x
x * (cos(64)) = 7
x * (cos(64)) / (cos(64)) = 7 / (cos(64))
x = 7 / (cos(64))
x = 7/0.43837
x = 15.968246
