Answer:
Step-by-step explanation:
There is no such thing as the inverse Law of Cosines. You CAN use the law to find a missing angle, which is found by finding the inverse cos of a ratio. For example, if you have all 3 sides of a non-right triangle and you are looking for the measure of an angle, you would do all the required math, and in the end you would have that cos(x) = some fraction. Take the inverse cos on your calculator of this fraction and get the angle value.
In other words, the Law of cosines can be used to find both a missing side OR a missing angle.
You can do this by dividing the top number (the numerator) by the bottom number (denominator). You can use a calculator, but your pic is to blurry for me to read the problem.
