Answer:
Question 1 is --- 135°
Question 2 is---- 82°
Step-by-step explanation:
they are both corresponding angles
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:
x-12≤7
x≤19
Step-by-step explanation:
less than means it comes after
x-12
is at most means less than or equal to
x-12≤7
Add 12 to each side
x-12+12≤7+12
x≤19
