Answer:
12.4 ft
Step-by-step explanation:
Everything is done right so far.
Now to calculate the height of the tree, 12tan46, put the equation into a calculator.
Either a graphing calculator (make sure it is in degrees, not radians),
or the one on your phone (turn your phone landscape in the calculator app to get the trig functions.))
12tan46= 12.4 ft
60 percent because if you divide if you multiply 18 by 100 it gives you 18000 then divide it by 30 it gives you 60
-2x-x+5=-2x+3x-10x cancel equal terms
-x+5=3x-10x collect like terms
-x+5=-7x move terms
-x+7x=-5 collect like terms
6x=-5 divide both sides by 6
x=-5/6 or 0.83
