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
