Answer:
x = 4.4
Step-by-step explanation:
cos theta = adjacent side / hypotenuse
cos 24 = y/x
cos 24 = 4/x
x cos 24 = 4
x = 4/cos 24
x =4.378545114
Rounding to 1 decimal place
x=4.4cm
We can use cosine to find x as we're given y (adjacent) and the angle. This is also a right triangle.
cos24=4/x
x=4/cos24
x=4.4
