Well, for any prism, it is the lateral area + the area of two ends.
Answer:
Step-by-step explanation:
Solving For V.
2v=−10x
You need to divided both sides by 2.
2v
/2 = −10x
/2
v = −5x
Answer:
v = −5x
Add all the angle and =to 180 because all the angle in a triangle add up to 180 then put all numbers on one side and all x terms on the other side then you find x
I think its D but im not sure
Answer:

Step-by-step explanation:
Connect points I and K, K and M, M and I.
1. Find the area of triangles IJK, KLM and MNI:

2. Note that

3. The area of hexagon IJKLMN is the sum of the area of all triangles:

Another way to solve is to find the area of triangle KIM be Heorn's fomula, where all sides KI, KM and IM can be calculated using cosine theorem.
