Answer:
3,231 feet
Step-by-step explanation:
Find the difference between the two heights by subtracting them:
2933 - (-298)
2933 + 298
= 3231
So, the difference in altitude is 3,231 feet
Answer:
d
Step-by-step explanation:
sin 55° = cos 25°
because they complete each other to 90°
The barn, the ground, and the ladder form a right triangle. If we represent the height on the barn by y, then the Pythagorean theorem tells us
... hypotenuse² = (side1)² + (side2)²
... (12 ft)² = (3 ft)² + y² . . . . . . . . . . . . fill in given information
... 144 ft² - 9 ft² = y² = 135 ft² . . . . . .subtract (3 ft)²
... y = 3√15 ft ≈ 11.6 ft . . . . . . . . . . . take the square root
The ladder reaches 11.6 feet high on the barn.
