Think of the 13-ft length of the ladder as the hypotenuse of a right triangle. Represent the horiz. distance from foot of ladder to base of tree by x, or 5 ft.
Represent the vert. dist. from base of tree to top of ladder by y, which is unknown.
Then (13 ft)^2 = (5 ft)^2 + y^2, or
169 ft^2 = 25 ft^2 + y^2. This simplifies to y^2 = 144. Thus y = + 12 feeet.
Note: Please pay attention to your spelling: "lader i up agenst a tree" should be "the top of a 13-ft ladder is placed against a tree."
Answer:
{w} is the SUBSET of {s,w,n,t,c}
Step-by-step explanation:
SUBSET: Any set P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.
i.e P ⊂ Q
Here, the given set Q = {s,w,n,t,c}
Also, set P = {w}
Now,as the element w of set P is also an element of set Q.
⇒ P is the SUBSET of Q
⇒ P ⊂ Q
⇒ {w} ⊂ {s,w,n,t,c}
Hence, {w} is the SUBSET of {s,w,n,t,c}.
