Answer:

Step-by-step explanation:

tan Ф = opposite side  divided by the adjacent side    

tan Ф = opp/adj    in your problem Ф is x

tan x = 4/9        

x = arctan (4/9)      on your calculator arctan is might look like inverse tan

                       or you might have to use the 2nd (second) button and then tan

x = inverse tan (0.44444 repeating)     try it on your own calculator

 = 23.962488974578183                     rounds up to 24.0

 = 24.0
