Answer:

Step-by-step explanation:




If
then:

Answer:
1-k^2
Step-by-step explanation:
tan A= sin A/cos A
(sin A)(cos A)(sin A/cos A)=(sin A)^2
(sin A) ^2 + (cos A) ^2= 1
(sin A) ^2=1-(cos A) ^2
(sin A)^2= 1 - k^2

Answer:
7 1/2 miles
Step-by-step explanation:
The distance to the airport is 10 miles
The distance to the lake is 3/4 the distance to the airport
d =3/4 *10
d =30/4 = 7 2/4 = 7 1/2 miles
magnitude = sqrt(6^2+4^2)
= sqrt ( 36+16)
=sqrt (52) = 7.2
angle = tan^-1(6/4) = 56 degrees
