Math Problem Statement

solve for x

Solve for x in the given right triangle where the angle is 27° and the hypotenuse is 13.

Solution

The image shows a right triangle with an angle of 2727^\circ, the hypotenuse of length 13, and the side opposite the angle xx. To solve for xx, we can use the sine function, since the sine of an angle in a right triangle is the ratio of the opposite side to the hypotenuse:

sin(θ)=oppositehypotenuse\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}

For this triangle:

  • θ=27\theta = 27^\circ
  • Opposite side = xx
  • Hypotenuse = 13

Thus, we set up the equation:

sin(27)=x13\sin(27^\circ) = \frac{x}{13}

Now, solve for xx:

x=13×sin(27)x = 13 \times \sin(27^\circ)

Using a calculator:

x13×0.4540=5.902x \approx 13 \times 0.4540 = 5.902

So, x5.9x \approx 5.9.
