Answer:
B at 4.7
Step-by-step explanation:
The square root of 22 is 4.69
So, Round it up to 4.7
The cosine for ∠A is .
Option: A.
<u>Step-by-step explanation:</u>
From the given diagram,
Opposite = 8 ft.
Adjacent = 5 ft.
In trigonometry, the formula for cosine = .
We are not given with hypotenuse. So we have to find the hypotenuse using Pythagorean Theorem
.
.
hypotenuse = .
cosine = .
Multiply in both numerator and denominator,
The cosine for ∠A is .
For this case we have the following equation:
We want to clear x:
For this we must follow a series of steps, the first consists of adding 4x to both sides of the equation to obtain:
In this way, the variable term remains on one side of the equation.
Thus, the first step will be:
Add 4x to both sides
