Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:

Hence, option D is correct.
Step-by-step explanation:
Given
Determining the length of LM
The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)








Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

Hence, option D is correct.

90°-50°=40°
Answer:
srry its 31 and 10
Step-by-step explanation:
The equation is equivalent to x2/25 + y2/(25/<span>9)</span>= 1, it is an ellipse equation
the center is C(0,0)
a=5; b= 5/3, so a>b it is a horizontal major axis type (the x-axis)
all that you do is to find all characteristics by following all required formula
