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:
The answer is
<h2>

</h2>
Step-by-step explanation:
The statement
y varies inversely with x is written as

where k is the constant of proportionality
To find k substitute the values of x and y into the equation
From the question
y = 4
x = 6
We have

Cross multiply
k = 4 × 6
k = 24
So the formula for the variation is
