Answer:
Step-by-step explanation:
The 2 lines are y=2x+12 (slope of 2 y-intercept at 12) and y=26 (line at y=26).
intersection= (7,26)
It all depends upon what other things are given If hypotenuse is not given, in cosine or reciprocals are useless. In that case only tan and cot will be equally convenient if adjacent sides are given.
8u+3<19 subtract 3 from both sides
8u<16 divide both sides by 8
u<2 so
-9 is in the solution set u=(-oo, 2)
You have to include a drawing that relates the distace between de towers and some angles.
I will use one that gives the angle from the base of Seafirst Tower to the top of Columbia tower as 53 degress.
This lets you calculate the distance between the towers, d, as
tan(53) = 954 / d => d = 954 / tan(53) = 718.89ft
The same drawing gives the angle from the the base of the Columbtia tower to the top of the Seafirst Tower as 27 degrees.
Tnen, tan(27) = height / d => height = d*tan(27) = 718.89*tan(27) = 366.29 ft
Answer: 366.29 ft
