M is the midpoint of LN. what is LM?
2 answers:
Answer: LM = 6 units.
Step-by-step explanation: Given that the point M is the mid-point of the line segment LN shown in the figure.
We are to find the length of LM.
From the figure, we note that
LM = 3x and MN = 2x + 2.
Since M is the mid-point of LN, so it will divide LN in two equal parts.
That is, we must have
Therefore, we get
Thus, LM = 6 units.

Answer:
Step-by-step explanation:
By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.
Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.
So, in this case you need to use the following Trigonometric Identity:
In this case, you can identify that:
Substituting values, and solving for "x", you get:
Therefore, the length of BC rounded to nearest tenth, is:
