Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
Your answer is at the top good luck!
Answer:
.
Step-by-step explanation:
The linear approximation is given by the equation
Linear approximation is a good way to approximate values of as long as you stay close to the point , but the farther you get from , the worse your approximation.
We know that,
Next, we need to plug in the known values and calculate the value of :
Then
