Angle of Elevation: Airplane Problem

[nycmathguy]

Section 4.7

Part (a)

sin (theta) = 6/x

arcsin[sin(theta)] = arcsin(6/x)

theta = arcsin(6/x)

Part (b)

For this part, I simply replace x with 12 miles and evaluate the function in (a) and then repeat and do the same when x = 7 miles.

You say?

yes

yes

Ok. Now, I'm cooking with gas, like Richie Cunningham is known for saying on Happy Days.
