I think it must be the right triangle so
x=height of the antenna
tan(66)=x/50
x=50*tan(66)
x=1.33 ft
->the height of the antenna = 1.33 ft
hope it is the correct answer because you didn't provided me enough information.
No the inequality symbol only changed when you divide a negative number from both sides.
86+41=127=x
360-2(127)=106
y=106
