Answer:
A good estimate for the slope is 95/60
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
From the graph take the points
(0,0) and (80,125)
substitute
simplify
Multiply by 3.75 both numerator and denominator
therefore
A good estimate for the slope is 95/60
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. The correct option is B.
<h3>What is the Law of Cosine?</h3>The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
The length of the sidelink b using the cosine rule can be written as,
Hence, the correct option is B.
The complete question is:
Consider ABC with the measure of angle B equal to 60 degrees, and side lengths a=4 and c=5. Which option lists an expression that is equivalent to the length of side b?
