4) 41% of 78 is what?

Answer = 31.98

Work:

x = 41/100 x 78

x = 3198/100

x = 31.98

6) 58% of what is 63.4?

The number is = 109.31

Explanation:

Let the number be = x

58/100 (x) = 63.4

x = 63.4 x (100/58)

x = 6340/58

x = 109.31

**Answer:**

756.36 meters

**Step-by-step explanation:**

Draw a diagram. Let's call the horizontal distance from the top of the mountain to the closest point x.

Using tangent = opposite / adjacent, we can write two equations:

tan 35.3° = h / x

tan 25.76° = h / (x + 500)

Solve for x in the first equation and substitute into the second.

x = h / tan 35.3°

tan 25.76° = h / ((h / tan 35.3°) + 500)

Solve for h.

tan 25.76° (h / tan 35.3°) + 500 tan 25.76° = h

500 tan 25.76° = h (1 − (tan 25.76° / tan 35.3°))

500 tan 25.76° tan 35.3° = h (tan 35.3° − tan 25.76°)

h = 500 tan 25.76° tan 35.3° / (tan 35.3° − tan 25.76°)

h ≈ 756.36 meters
