Answer:
Step-by-step explanation:
Assume your triangle has the dimensions shown below.
Before we can use the Law of Sines, we must find ∠C.
1. Calculate ∠C
2. Calculate b
Use the Law of Sines
176.71cm^2
Area of a circle is pi*radius^2
your radius is given to you, which is 7.5
pi*7.5^2 in a calculator gives you 176.71
x = 5.2 or x = -5.2
