Question 1154562
On a flat sidewalk, you lean a ladder against a wall. The base of the wall makes a 900 -----  I'll assume you mean 90 degs ----
angle with the sidewalk. The base of the ladder makes a 50 degree angle with the sidewalk. ------ Dangerous arrangement. ------
==============================
You measure the distance from the base of the ladder to the wall and it is 12 feet.
Answer each of the following questions please. Clearly indicate your answers with 5 digits after the decimal, except for whole numbers.
a) How long is the ladder?
L = ladder's length
cos(50) = 12/L
-------------------
b) How high up the wall does the ladder reach?
h = L*sin(50)
-------------------
c) What angle does the ladder make with the wall?
Think about it.
---------------------
d) Please - draw a diagram and show all calculations.
No.
------------------
e) Explain whether any two angles in your diagram represent a cofunction and
prove your statement with values of sine and cosine.
sin(angle) = cos(90 - angle)
