remaining side, in feet?

Answer:
Step-by-step explanation:
Given that,
→ Perpendicular (x) = ?
→ Hypotenuse (h) = 9 feet
→ Base (b) = 2 feet
Now by using the Phythagoras theorem,
→ (Hypotenuse)² = (Perpendicular)² + (Base)²
→ (h)² = (x)² + (b)²
→ (9)² = (x)² + (2)²
→ 81 = (x)² + 4
→ (x)² = 81 - 4
→ (x)² = 77
→ [ x = √(77) ]
Thus, length of remaining side is √(77) ft.

Step-by-step explanation:
Since the inequality is already written in y=mx+b, you can easily graph the line. +3 is the y intercept, so one point would be (0,3). -2 resembles the slope, so diagonally to the left, you would go up 2 and across 1. Also, since the sign is "<" you would graph with a dotted line. Then to know which side to shade, I always use the coordinate (0,0). I plug in 0 for both x and y to see if (0,0) satisfies the inequality. In this case it does, so you would shade on the side where (0,0) is located.
