Math Problem Statement

Find y. Round to the nearest tenth: A right triangle with an angle of 27 degrees, an adjacent side measuring 350 ft, and an unknown opposite side y.

Solution

We are dealing with a right triangle, where:

  • yy is the side opposite to the 2727^\circ angle,
  • 350ft350 \, \text{ft} is the adjacent side (base of the triangle),
  • xx is the hypotenuse, and
  • We need to find yy, rounding the answer to the nearest tenth.

We can use the trigonometric function tangent (tan\tan) to solve for yy, because:

tan(θ)=oppositeadjacent\tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}

For this triangle:

tan(27)=y350\tan(27^\circ) = \frac{y}{350}

Now, solving for yy:

y=350×tan(27)y = 350 \times \tan(27^\circ)

Let me calculate that for you.

y350×0.5095178.3fty \approx 350 \times 0.5095 \approx 178.3 \, \text{ft}

Thus, the value of yy is approximately 178.3 feet.
