I NEED HELP PLEASE IT WOULD REALLY MEAN AOT !!!!

NO ZOOMS OR LINKS!!!!

Answer 1

20.78

Explanation:

sin a = perpendicular/ hypotenuse

where a is the base angle

here a = 60

sin 60 = 18/ x

since,

`\sin(60) = \ ( √(3) )/(2)`

`( √(3) )/(2) = (18)/(x)`

√3 x = 36

x = 36/ √3

x = 36/ 1.732

x = 20.78
