Here you go :) I sent the work in the picture below
Answer:
+4 and -4
Step-by-step explanation:
(x^2)-14=2
(x^2)-14-2=0
(x^2)-16=0
(x-4)(x+4)=0 = True
The best approach to this is to use the law of cosine which is stated as
c2 = a2 + b2 â’ 2ab cos(C)
distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value.
Hence c²=176.27²+222.34² -2*176.27*222.34cos38.59°= 138.71 miles
