Right angle trigonometry What trig ratio do we use amp Identify the hypotenuse opposite or adjacent giving brainliest class=

Answer:

x = 3.7

Step-by-step explanation:

Reference angle = 24°

Hypotenuse = 4

Side adjacent to reference angle = x

We would apply the trigonometric ratio, CAH, which is:

Cos 24 = adj/hyp

Cos 24 = x/4

4 × Cos 24 = x

x = 3.65418183 ≈ 3.7 (to nearest tenth)
