What are the ratios for sin A and cos A? The diagram is not drawn to scale.
trapecia [35]

Answer:

C

Step-by-step explanation:

Sin represents opposite/hypotenuse. Thus, when A is the reference angle, 21 is the measure of the opposite side (CB) and 29 is the measure of the hypotenuse (AB).

Cos represents adjacent/hypotenuse. Therefore, when A is the reference angle, 20 is the measure of the adjacent side (AC) and 29 is the measure of the hypotenuse (AB).

Please help , how would you solve this
DerKrebs [107]
For the first one:
t \:  -  \: 2e = 20
you change the subtract 2 to add 2 on both sides. so it looks like the picture above. Then you would add 20 + 2 to equal 22. Then you divide that by 1 (from the t). that equals 22, so thats the answer.
t = 22

Use the Special Right Triangle to evaluate sin 60°, cos 60° and tan 60°. Your answers should be exact (not a decimal).
BigorU [14]
Sin 60 = \sqrt{3}/2
cos 60 = 1/2
tan 60 = \sqrt{3}

The answer to your question is D. I hope that this is the answer that you were looking for and it has helped you.

Which system of inequalities is represented by the graph
Lera25 [3.4K]

Answer:

y ≤ 2x + 4 and x + y ≥ -6

Step-by-step explanation:

Graphing a system of inequalities is similar to graphing linear functions.  It is best to have equations in the form of y = mx + b where m = slope and b = y-intercept.  Looking at the graph, you can see that there is one line going uphill (positive slope) and one going downhill (negative slope).  There are two y-intercepts, one from each line at (0,4) and (0, -6)  So, only the top two equations have a y-intercept equal to 4 and -6.  Then, you can find the slope of each line by choosing two points on the same line and using rise/run to find the change in 'y' over the change in 'x'.  

Line #1 (uphill):  (-2, 0) and (0, 4) = 4-0/0- -2 = 4/2 = 2

The only answer with a positve 2 slope and y-intercepts of 4 and -6 is the second one, so that is your answer.
