Question

TRIG :(((
A lamp post, CAB, bent at point A after a storm. The tip of the lamp post touched the ground at point C, as shown below.
What is the height, in feet, of the portion AB of the lamp post?


12 tan 45°

12 by tan 45 degrees.

12 by cos 45 degrees.

12 cos 45°

Answer 1

remember the definition of \(\tan{X}\)? It's \[\tan{X}=\frac{AB}{BC}\] where X=45. Then:\[AB=BC\tan{45}\]

Answer 2

is it over or times?

Answer 3

AB=BC*tan45

Answer 4

thank you :D
