Math Problem Statement

Solve for x. Round to the nearest tenth, if necessary.

Solution

To solve for xx, we can use trigonometric ratios since the triangle involves a right angle (W\angle W) and the given angle of 5252^\circ. The sides provided and the one to find are associated with the given angle 5252^\circ.

Step 1: Identify sides relative to T=52\angle T = 52^\circ:

  1. xx is the hypotenuse of the triangle.
  2. 9696 is the adjacent side to the angle.

Step 2: Select the appropriate trigonometric ratio.

Using the cosine function (since cosine involves adjacent and hypotenuse): cos(θ)=adjacenthypotenuse\cos(\theta) = \frac{\text{adjacent}}{\text{hypotenuse}}

Here: cos(52)=96x\cos(52^\circ) = \frac{96}{x}

Step 3: Solve for xx.

Rearranging the equation to solve for xx: x=96cos(52)x = \frac{96}{\cos(52^\circ)}

Step 4: Calculate xx.

Using a calculator: cos(52)0.6157\cos(52^\circ) \approx 0.6157

So: x=960.6157155.9x = \frac{96}{0.6157} \approx 155.9

Final Answer:

x155.9x \approx 155.9
