Use the Pythagorean theorem
H = sqrt (8^2 + 15^2)
H = sqrt(64 + 225)
H = sqrt(289)
H = 17 km
Answer:
- 2 ≤ n < 8
Step-by-step explanation:
The closed circle at - 2 indicates that n can equal - 2
The open circle at 8 indicates that n cannot equal 8
Otherwise n can be all value between - 2 and 8 including - 2, thus
