Find the missing side or angle. Round to the nearest tenth.
A=72°
C= 50°
a=40
c=[ ? ]

Rounded to the nearest tenth: c = 32.2

Step-by-step explanation:

We can use the Law of Sines to solve the problem.

Recall this useful Law for triangles:

so we can use it for the data and unknown of our case (, , , and c what we need to find:

and this rounded to the nearest tenth is: c = 32.2
