Answer:

y = 19.4

x = 14.1

Explanation:

Data

  • the opposite side to the angle 54° is y
  • the adjacent side to the angle 54° is x
  • the hypotenuse is 24 units length

From definition:

sin(54°) = opposite/hypotenuse

Replacing with data and solving for y:

sin(54°) = y/24

sin(54°)*24 = y

19.4 = y

From definition:

cos(54°) = adjacent/hypotenuse

Replacing with data and solving for x:

cos(54°) = x/24

cos(54°)*24 = x

14.1 = x
