Consider, please, this solution. If it is possible, check it in the alternative sources.
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:
Yintecept is 0
Step-by-step explanation:
because it's y= Mx+b
but this one is y = mx
It's an isosceles triangle so that you bottom angles are 71 add those then subtract whatever the sum of 71 + 71 is minus 180. and there's the third angle
