A ladder 5m long, leaning against a vertical wall makes an angle of 65° with the ground.
a. ) How high on the wall does the ladder reach?
b. ) How far is the foot of the ladder from the wall?
c. ) What angle does the ladder make with the wall?
a.) sin 65 = a/5
a = sin 65(5)
a = 4.53 m
b.) cos 65 = b/5
b = cos 65(5)
b = 2.11 m
c.) 180 - 90 - 65
c = 25°

A squirrel sits atop a 14ft tall tree. He spies a nut on the ground some distance away. After careful measurements, he determines the nut is 74° from the base of his tree. How far away is the nut from:
a. ) The base of the tree
b. ) The squirrel
a.) tan 74 = A/14
A = tan 74(14)
A = 48.82 ft
b.) cos 74 = 14/B
B = 14/cos 74
B = 50.79 ft

A prince has arrived to rescue a princess standing in a tower balcony 15m up across a moat 12m wide. He knew the princess was high up and there was a moat, so he brought the longest ladder in the kingdom; a 20m monster.
a. ) Is the ladder long enough?
b. ) If the top of the 20m ladder touches the balcony, how far away from the tower wall is the bottom of the ladder?
c. ) What is the angle between the ground and the ladder?
a.) √15² + 12²
= 20 - 19.21m
Yes, with an excess of 0.79m
b.) √20² - 15²
B = 13.23 m
c.) 20/sin 90 = 15/sin 6
15(sin 90)/20 (shift sin)
c = 48.59°
142
The angle of elevation from a point 43ft from the base of a tree on level ground to the top of the tree is 30°. What is the height of the tree?
43/sin 60 = h/sin 30
43(sin 30)/sin 60
h = 24.83ft

What if a restaurant needed to build a wheelchair ramp for its customers? The angle of elevation for a ramp is recommended to be 5∘. If the vertical distance from the sidewalk to the front door is two feet, what is the horizontal distance that the ramp will take up (x)? How long will the ramp be (y)? Round your answers to the nearest hundredth.
```
θ = 180 - 90 - 5
θ = 85°
```
x = 2/sin 5 = y/sin 85
x = 2(sin 85) / sin 5
x ≈ 22.86 ft.
y = 2/sin 5 = y/sin 90
y = 2(sin 90) / sin 5
y ≈ 22.95 ft.
