Answer:
The point-slope form of the equation is:
Step-by-step explanation:
Given
- point (3, -5)
- slope = -3
We know the point-slope form of the line equation is
where m is the slope
substituting the values m = -3 and the point (3, -5)
Thus, the point-slope form of the equation is:
The length of the major arc LNM is
From the question,
We are to determine the value of the length of the major arc LNM
The length of the major arc LNM can be calculated using the formula
Where r is the radius
First, we will determine the value of the reflex ∠LKM
Reflex ∠LKM + ∠LKM = 360° (<em>Sum of angles at a point</em>)
From the given information,
∠LKM = 70°
Then,
Reflex ∠LKM + 70° = 360°
Reflex ∠LKM = 360° - 70°
Reflex ∠LKM = 290°
Also, from the question
r = 3 cm
Now, putting the parameters into the formula, we get
Then,
Hence, the length of the major arc LNM is
