3) From a point on the ground 12 ft from the
base of a flagpole, the angle of elevation
of the top of the pole measures 53º. How
tall is the flagpole?

Answer x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​x=\frac{4(7+y)}{5}x=​5​​4(7+y)​​

step-by-step explanation:

12x+8-x=12x-x+8=11x+8=11

Y= - 4x +3if you test it with any of the x values for example x=2: -4(2)+3 = - 8 + 3 = - 5you get the matching ^^^ y value
