Answer:
b.
Step-by-step explanation:
Answer:
.
Step-by-step explanation:
If a line passing through two points, then

Endpoints of segment MN have coordinates (0, 0) and (5, 1).
Slope of MN 
The endpoints of segment AB have coordinates
and
.

.
Slope of AB 




Product of slopes of two perpendicular segments is -1.
Slope of MN × Slope of AB = -1







Therefore, the value of k is
.
The balloon’s vertical distance above the ground is 570.3 feet
<h3>Angle of elevation and depression</h3>
Given the following parameters
The angle of depression = 36 degrees
Base distance = 785 feet
<h3>Required</h3>
vertical distance above the ground (H)
Using the SOH CAH TOA identity
tan 36 = H/785
H = 785tan36
H = 570.3 feet
Hence the balloon’s vertical distance above the ground is 570.3 feet
