The hikers 3 miles from the trailhead to the waterfall.
d1 = 3 miles
Then, the hikers made a right turn and hiked another 3 miles until they stopped for lunch.
d2=3 miles
We can solve the distance when they returned to the trailhead using Pythagorean theorem:
D ² =d1² + d2²
D² = 3² + 3²
D = 4.24
The distance is 4.24 miles.
The left side can be written as a square. We can take the square root, then subtract 1.
... (x +1)² = 17
... x +1 = ±√17
... x = -1 ±√17
Answer:
x = 74 degrees
Step-by-step explanation:
180 - 32 = 148
148 / 2 = 74
