[Right Triangles Only] SOHCAHTOA[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Define

Angle θ = 42°

Adjacent Leg = x

Hypotenuse = 15

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos42^\circ = \frac{x}{15}$ [Multiplication Property of Equality] Isolate x: $\displaystyle 15cos42^\circ = x$ Rewrite: $\displaystyle x = 15cos42^\circ$ Evaluate: $\displaystyle x = 11.1472$ Round: $\displaystyle x \approx 11.1$
