Would we label a triangle this way before doing sine/cosine/tangent?

No - It is labbelled to do the Pythagorean thereom
What is the ratio of cos<?

cos<?=76/95
Find the angle:
sin<x=0.5
What is x=30 degrees
Find the missing side length to the nearest tenth:

What is 8.3
Is this a right triangle? You must show me the proof.

What is no because 181 does not equal 225.
What is the correct label for side x?
What is opposite.
What is the ratio of sin<? 
sin<?=45/75
Find the missing angle:

What is 12 degrees.
Find the missing side length:

What is 8 yards.
Solve for x:

What is 8.6 m
Label the sides (o/a/h) using Vertex L (YOU MUST DRAW THE ENTIRE TRIANGLE ON THE Whiteboard). 
Ask teacher to check
What is the ratio of the tan<?

tan < = 40/75
Find <?

What is 37 degrees
Find the missing side length:

What is 15 inches
A triangle has sides of 10, 10, and 10. What type of triangle is it (acute/obtuse/right) or does it not form a triangle?
Acute!
The tangent equation is written for which angle?
tan<?=30/40 ?

What is <X
What is <?
What is 14 degrees
Find the length of the hypotenuse
(not x!)

What is 15.2
Solve for the missing angle to the nearest tenth:

What is 59.7 degrees
Draw, and label, a diagram to represent the following
A 12 foot ladder leaning against a building makes a 75 degree angle with the ground. How high up the building does it reach?
Ask teaccher to check
12 should be the hypotenuse
75 should be the angle on the bottom
A 30 ft guy wire is attached from the top of a pole to a peg on the ground. (A guy wire is used for lateral stability.) The peg is 18 feet away from the bottom of the pole. What angle does the wire make with the ground? Draw a diagram and solve
What is 53.1 degrees
Find the exact value of x in the 45-45-90 triangle

What is 20 / sqrt2 or 10 sqrt2
ask teacher to check your answer
In a right triangle the hypotenuse is 4 sqrt3, and a leg is 4. What is the length of the other leg, in simplified radical form? (No decimals!)
square root of 32 which simplifies to
4 sqrt 2
