Given:
bottom of the plank or ground is 9 feet from the wall
length of the plant is 41 ft
height of the wall is unknown.
Let us use the Pythagorean theorem.
a² + b² = c²
a² + (9ft)² = (41ft)²
a² + 81 ft² = 1,681 ft²
a² = 1,681 ft² - 81 ft²
a² = 1,600 ft²
√a² = √1,600 ft²
a = 40 ft
The height of the wall is 40 ft.

Answer:
1
Step-by-step explanation:
m= (y-y1)/(x-x1)
Points are (-10, -20) and (1, -9)
m= (-20+9)/(-10-1)= (-11)/(-11)= 1
m=1 to replace ? mark
