Sketch a well labelled diagram.
You will be able to use the COSINE LAW for the length of the unknown side :)
Let me know if you are unable to find one of the answers.
The question worked out very nicely.
Casey and Tamary are standing 14 ft. apart from each other and looking up at a kite that is flying between them. Casey is flying the kite on a 70 ft. string at an angle of 72 degrees with the ground. How far is Tamary from the kite?
a. 73.1 ft.
b. 67.0 ft.
c. 75.5 ft.
d. 69.2 ft.

the height of the kite is ... 70' sin(72º)
the distance from Casey to directly under the kite is ... 70' cos(72º)
find the distance from Tamary to directly under the kite
... 14' - Casey's distance
use Pythagoras (a^2 + b^2 = c^2) to find Tamary's distance from the kite
the distance from Casey to directly under the kite is ... 70' cos(72º)
find the distance from Tamary to directly under the kite
... 14' - Casey's distance
use Pythagoras (a^2 + b^2 = c^2) to find Tamary's distance from the kite
Do we have an answer for this?
