Answer: A: 90 degrees
Step-by-step explanation:
The measure of angle C is 90 degrees as BD and BC are chords to the circle.
Let x ft be the length of the ladder, then the distance from the ground to the top of it will be x-1 ft.
If the distance from the bottom of the ladder to the building is 3 ft, then we can apply Pythagoras:
x² = (x-1)² + 3² . Expand:
x² = x² - 2x + 1 + 9
x² = x² - 2x + 10
x² - x² = - 2x + 10
0 = - 2x + 10
2x = 10 and x = 5 ft

Answer:
15%
Step-by-step explanation:
Percent is (usually) out of 100. So since the unit is already 100 you can just look at how much she did lose. (^-^)
Answer:
y = -x + 3
Step-by-step explanation:
y = x - 3 This equation has a slope of 1
A line that would be perpendicular to the above line would then need a slope of -1
If the line has a slope of -1 and passes through (2, 1) then we can plug into
y = mx + b to get the 'b' value
1 = (-1)(2) + b
1 = -2 + b
3 = b
Equation would be y = -x + 3
