Question

In my class were doing SOH CAH TOA and Angle of Elevation and Depression, but I don't understand this word problem

Answer 1

1,442.9203034232

Explanation:

Because the blimp has an angle of depression of 12, we can conclude the inside angle is 78

90-12=78

then we can use cosine to find the hypotenuse

300/cos78=1,442.9203034232
