Using Pythagorean Theorem, you can find that the diagonal pipe would have to be 17 feet long to bisect the yard. sqrt(8^2+15^2)=17
F (x) = 5(4) ^x Is the right answer
Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04
for a line the letters can be either way it can be DC or CD either way it is the same line being represented. because the other lines are represented by other letters you can be either order.
