For the hiker whose angle of depression is 37°, you can write:

tan (37°) = 525m / x, where x is the horizontal distance from the hiker to the landmark

=> x = 525 / tan (37) = 696.7m

For the hiker whose angle of depression is 22°, you can write

tan (22°) = 525m / y, where y is the horizontal distance from the hiker to the landmark

=> y = 525m / tan (22) = 1,299.4 m

The distance that separate both hikers is x + y = 696.7 + 1,299.4 = 1,996.1m ≈ 1,996m (rounded to the nearest whole meter)

Answer: 1996m
