The correct answer is 28 because all numbers add up to 200 and the number saying that she doesn't attend either is 56, half of 56 is 28. Voila
The total surface area of this square based pyramid is 125 squared inches :)
Answer:
9.27•10^5
Step-by-step explanation:
Answer: 1,509.52 meters
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of depression from one mountain to another, the opposite side is the difference between heights, and the adjacent side (x) is the horizontal distance between the two summits.
Replacing with the values given:
Tan 15.9 = 430/x
Solving for x:
x = 430/ (tan 15.9)
x= 1,509.52 meters
