Answer:
True.
Step-by-step explanation:
Any number that can be written as a fraction a/b where a and b are integers (neither a nor b= 0) is rational,
For example 3 ( = 3/1) , 1/3 , 5/10 are all rational.
Given:
Length of the ladder = 20 ft
Distance between base of the ladder and wall = 4 ft
To find:
The angle measure of the ladder to the ground to the nearest degree.
Solution:
Ladder is the hypotenuse of a right triangle. Here, we have,
Hypotenuse = 20 ft
Base = 4 ft
In a right angle triangle,



Taking cos inverse on both sides, we get



Therefore, the correct option is A.
Answer:
52.02 ft
Step-by-step explanation:
We can use equation tan θ = opposite/adjacent to solve for the opposite side x.
tan40° = x / 62
62tan40° = x
x = 52.02 ft
