Answer:
height of the wall = 9.79 m
Step-by-step explanation:
This form a right angled triangle.
Hypotenuse = length of the ladder = 10 m
Base = length from foot of ladder to wall.
Altitude = height of the wall
Pythagorean's theorem,
base² + altitude² = hypotenuse²
2² + altitude² = 10²
4 + altitude² = 100
altitude² = 100 - 4
altitude² = 96
altitude = √96 = 9.79 m
Answer:
(i) Center = (-1, -2)
(ii) Radius = 5 units
General Circle Equation:
<u>Where</u>:
- (h, k) is the center points
<u>Rewriting the equation</u>:
<u>Identify the following</u>:
- (h, k) = (-1, -2), radius = 5 units
Ok so ax + 3b = 2f
If you take '3b' away from both sides,
This means that ax = 2f -3b
And so once you divide both sides by a, you get:
x = (2f-3b)/a
Hope this helped
