Answer:
x<-9
Step-by-step explanation:
Adjacent, cosine again.
a = c cos B = 13 cos(16+45/60) = 13 cos(16.75) = 12.448
Choice a
Answer:
= 5.196 i
Step-by-step explanation:
The problem tells us to find the square root of -98 +71
√(-98 + 71)
= √(-27)
Which is an imaginary number
=√(-3^3)
Lets remember that, √(-1) = i
= i*3√(3)
= 5.196 i
