Answer:
26.9 ft
Explanation:
So this answer is going to require one of the trigonometric functions, which is the ratio of sides of a triangle. So I attached a diagram to my answer, which is depicting the given information and hopefully this should be able to help a bit.
Anyways, we know the hypotenuse, an angle, and the opposite side of the angle. There is a trigonometric function which is defined as:
. We can use the sine function to solve for the opposite side. So let's plug in known values into this equation:
Known Values: theta=85 degrees, hypotenuse = 27 ft
![sin(85)=(opposite)/(27 ft)](https://img.qammunity.org/2023/formulas/mathematics/high-school/hodgu23nzr0r729je7z5hmwmam7utp7uzq.png)
Multiply both sides by 27 ft]
![sin(85)*27ft=opposite](https://img.qammunity.org/2023/formulas/mathematics/high-school/o0x2ygkfz5024z9j6e58343duyfwojxk8b.png)
Now you can approximate the value of sin(85) using your calculator, and make sure it's in degree mode not radian mode.
![0.996194698*27ft\approx opposite](https://img.qammunity.org/2023/formulas/mathematics/high-school/gxbcrn9i8ldua5a2ra6wu27q6ko6o9bvm1.png)
Simplify

Rounding this to one decimal place makes it
