The length of the ladder is approximately 3 m. The correct option is the first option 3
<h3>Calculating the length of a ladder</h3>
From the question, we are to calculate the length of the ladder.
From the given information,
The ladder makes an angle 20° with the ground
and
The foot of the ladder is 3 m from the wall
This scenario gives a right triangle where the hypotenuse is the ladder and the adjacent is the distance of the foot of the ladder from the wall.
Let the length of the ladder be x
Thus,
Using SOH CAH TOA
We can write that
cos 20° = 3 / x
x = 3/(cos 20°)
x = 3.19
x ≈ 3 m
Hence, the length is approximately 3 m

Answer:
126
Step-by-step explanation:
21 + 4 = 25 (blue plus white marbles)
150/25 = 6 (all the marbles divided by how many we know are white and blue)
21 x 6 = 126
3 ft by 5 ft
A = l • w 3 • 5 = 15
P = l + w + l + w 3 + 5 + 3 + 5 = 16
Answer:
3 feets
Step-by-step explanation:
Given that :
Entire walkway uses 6 feets of brick
Width of walkway = x
Width of walkway is the same along both sides ;
SINCE, the number of sides of the walkway = 2 and each side is the same
Hence,
x + x = 6 feets
2x = 6 feets
x = 6 feets / 2
x = 3 feets
Step-by-step explanation:We are given with two functions: f(x) = 9x - 2 and g(x) = -x + 3. In this problem, the expression of f(g(x)) is asked. We first substitute g(x) to f(x) resulting to f(-x + 3) = 9 (-x + 3) - 2 equal to -9x + 27 -2 or f(g(x)) = -9x + 25.
