I've been stuck for two days

the top of a tree makes angles s and t with points k and l on the ground, respectively, such that the angles are complementary. point k is x meters and point l is y meters from the base of the tree.

in terms of x and y, find the height of the tree. include your work. hint: what is ∠lgm?
if s = 38° and y = 3 meters, calculate the height of the tree, rounded to two decimal places.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
