Answer:
Step-by-step explanation:
For one line to be perpendicular to another, their slopes must multiply to -1. So, we really want the line with slope 
that passes through the point 
.
Recall the point-slope form of a line. If you have a point 
and a slope 
, the line through that point with the given slope is 
. Plugging in our given point and slope gives our line: 
(point-slope form).
We can convert this line to slope-intercept form, the most common form by expanding the right side and adding 
to get 
by itself:
M<1 = 360 / 3 = 120
m<2 = 120/2 = 60
m<3 = 180 - 90 - 60
m<3 = 30
answer

Answer: The ladder is 5.3 m long
Step by step solution
1. Draw out the scenario, ie a right triangle where the hypotenuse is the ladder, the wall is 4.5m and the angle the ladder and the ground makes 58 degree.
2. Soh, Cah, Toa
The wall is opposite, the ground is adjacent, and the ladder is hypotenuse
Sine (58) = 4.5/h
3. Solve for hypotenuse
h * sine (58) = 4.5
h = 4.5/sine (58)
h = ~ 5.3 m
