Answers

1
To solve this problem, I will
Tan 2.5/5
Sin 2.5/5
Tan-1 2.5/5
Sin - 1 2.5/5
2
Set up your formula
Cos 57 = y/15
Cos 57 = 15/y
Sin 57 = 15/y
Sin 57 = y/15
3
Which method will I use to solve for the unknown side?
Sin
Pythagoras
Tan
Cos
4
How will you solve this?
Sin
Cos
Pythagoras
Tan
5
What is wrong with this diagram?
No mountains are only 500m high
No way that angle is 15 degrees
Not enough info to solve for X
The hypotenuse is the same length as one side
6
Which function will you use - predict the result
Tan X = less than 45 degrees
Tan -1 O/A = less than 45 degrees
Tan X = more than 45 degrees
Tan-1 O/A = more than 45 degrees
7
A tangent value of 1.733 means
angle is less than 45 degrees
opposite side is longer than hypotenuse
adjacent side is longer than opposite
opposite side is longer than adjacent
8
To find the unknown angle, I will use
Pythagoras
Sine Law
3 angles add up to 180 degrees
Cosine Law
9
Which function will you use?
Cos 60
Sin 60
Tan 60
Pythagoras
10
Which functions could you use to solve for a or c?
Tan Cos
Sin Cos
Only Cos
Sin Tan
