Answer:
81
Step-by-step explanation:
Using PEMDAS/BODMAS, we will have to do the exponent first, which is .
Substitute the variable z with 6, since z = 6.
.
Thus, we will get
Solve the multiplication next.
Finally, add/subtract the numbers:

14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
