Answer: C. Bisect DE at G.
Step-by-step explanation:
- In a triangle, a median is a line segment drawn from a vertex to the midpoint of the opposite side of the vertex.
So, for triangle DEF , if we draw the median DG to the opposite side EF.
Here EF is the opposite side to vertex D.
So, G must be the midpoint of line segment EF.
So , we need to first mark G on EF.
i.e. we need to bisect EF at G.
So first step would be : Bisect EF at G.
Answer:
Tn = 5 +3(n -1)
Step-by-step explanation:
The first term of the sequence is a1 = 5. The common difference of the terms of the sequence is d = 8-5 = 3. The general term is ...
Tn = a1 +d(n -1)
Tn = 5 +3(n -1) . . . . . . fill in the values for this sequence.
