This trigonometry ratio relates hypotenuse and adjacent
What is cosine?
What Fortnite event recently ended on October 5th?
Doom Event
This is the key we need to hit first on the calculator to get an inverse trig ratio
What is the 2ND key
When using Trigonometry, the side length NEXT TO the angle is labeled with what abbreviation?
Adjacent
Find side length AB
AB = 8.40

Usually during the middle of October, what event has made consistent annual appearances since 2017?
Fortnitemares
When using Trigonometry, what formula is used to calculate the opposite side when given the Hypotenuse and an angle?
sin θ = O/H
35.10o
When using Trigonometry, the side across from the right angle is called?
Hypotenuse
Using trigonometry, and find the value for x:
Cos 37 = adj / hyp
Cos 37 = x / 11
11 Cos 37 = x
x = 8.789
In this right triangle
CAB, ∠A=90°. Determine ∠B to the nearest whole degree when CB=12.8 and AB=3.9.
Cos = 3.9/12.8
Cos-1 = 0.30
72 degrees
Why is Trig a helpful form of math?
You can determine sides and angles that are not able to be measured by devices.
How long is y?
y = 8.67
The only triangles that will work when using trig functions are:
Right Angle Triangles
Using trigonometry, find the value for x:
Tan 54 = opp / adj
Tan 54 = x / 5
5 times 1.376 = x
x = 6.880m
What angle does the rocket have to be launched at to reach the rocket base 300 km above Earth?
The 2024 Paintball Championship was near the end of the game and there was only one left standing on each team; Vox on the blue team and Vella on the red team.
Vella was standing behind a make shift wall, which was standing at 5m tall.
Vox was hiding in a snipers tower and because of all his hard work within the trigonometry unit he calculated the angle of elevation from top of his tower was 35 degrees.
Because Vella is an expert in trigonometry she knew that the angle of depression was 10 degrees at the base of Vox’s sniper tower.
Vella was trying to determine the height of Vox’s sniper tower to see if she could get a clear shot. Round to the nearest metre.

The function used to solve for the missing angle
Inverse trig functions (inverse sine, inverse cosine, inverse tangent)
Using trigonometry, calculate the value for x:
Sin 28 = opp / hyp
Sin 28 = x / 50
50 times .469 = x
x = 23.450m
In right triangle ADC, ∠D=90° and AD=5.6, AC=8.4. How big is the angle ∠ACD, rounded to one decimal place?
sin0 = O/H
sin0 = 5.6/8.4
sin0 = 0.66
sin-1 = 41.8 degrees
Find BOTH missing angles and the missing side.
Angle Z is the right angle.
Missing side = 29 cm or 28.777cm if you used trig.
Angle X = 44 degrees
Angle Y = 46 degrees
Did this loser get the correct answer or did he make an error during one of his steps?
he messed up dividing instead of multiplying
cos45(4.24) = x
