Find the value of x. round to the nearest tenth. the diagram is not drawn to scale.

What you should do in this case is to use the following trinonometric relationship:
 cosx = C.A / h
 Where
 C.O: Adjacent leg.
 h: hypotenuse.
 Substituting:
 cos (22) = (x) / (11)
 Clearing x:
 x = 11 * cos (22)
 x = 10.2
 
 The value of x is
 x = 10.2

If jon had $4.00 then takes away $2.25, then he should have $1.75 left. $4.00 - $2.25 = $1.75 hope this ; )
