Answer:
x = 399 m
Step-by-step explanation:
The cosine of an angle A can be calculated as:

In this case, the angle is 37°, its adjacent side is x and the hypotenuse is 500m. So, we can write the following equation:

Then, solving for x, we get:

Since cos 37 = 0.79, the value of x rounded to the nearest whole is:

Therefore, the answer is x = 399 m
