In ∆abc, if a = 8.75 centimeters, c = 4.26 centimeters, and m b = 87°, what is the length of b to two decimal places?
a. 8.92 centimeters
b.9.41 centimeters
c. 9.53 centimeters
d. 13.01 centimeters
e. 15.36 centimeters

This problem can be solved by making use of the Cosine Law. In general form, it is:
b2 = a2 + c2 - 2ac cos B

The given values are:
a = 8.75 cm
c = 4.26 cm
B = 87°

Plugging in the values:
b2 = 8.75^2 + 4.26^2 - 2(8.75)(4.26) cos 87
b = 9.53 cm

So, the answer is:
C. 9.53 centimeters

The answer should be c.
