[Right Triangles Only] SOHCAHTOA[Right Triangles Only] sinθ = opposite over hypotenuse

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = 64°

Opposite Leg = x

Hypotenuse = 11

Step 2: Solve for x

Substitute in variables [sine]: $\displaystyle sin(64^\circ) = \frac{x}{11}$ [Multiplication Property of Equality] Multiply 11 on both sides: $\displaystyle 11sin(64^\circ) = x$ Rewrite: $\displaystyle x = 11sin(64^\circ)$ Evaluate: $\displaystyle x = 9.88673$ Round: $\displaystyle x \approx 9.9$

Answer from: Quest

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
