Where’s the triangle, isn’t there supposed to be a picture with the question
Answer:
bh/2
Meaning :
base times height, halfed
The scenario described above is like dividing a right cone from the vertex down to the center for the base. The polygon that can be formed from the division or in this case slicing is a triangle. Thus, the answer to this item is letter B.
We can find out what LM is based on the fact that the bases of the 2 triangles are the same, this would also mean that the hypotenuse sides of the triangles should also be the same as well. Thus the sides of LM should also equal the sides of MN.
Another way, is to assume that the triangles are right angle ones, and use Pythagorean theorem to solve for the height and use that to solve for the hypotenuse.
We know that there are 7 days in a week, so just divide 68 ÷ 7 and you should get 9.71 which is approximately 10 weeks
