1
What is the cosine of angle A?
13/12
12/13
5/13
5/12
2
What are a, b, and c for 4x
2
-8x+16?
a = -4, b = 8, c = -16
Ima gonna put the quadratic formula on my card...
a = 4, b = 8, c = 16
a = 4, b = -8, c = 16
3
Which equation is equal to cos(35°)=x/5
The singles don't mingle
35/5 = 7
x = 5 / cos(35°)
x = 5 ⋅ cos(35°)
4
Which equation can you use to find x?
cos-1\frac{4}{3}
^{3^2+4^2=x^2}
^{4^2-3^2=x^2}
sin-1\frac{5}{4}
5
When do you use sin
-1
, cos
-1
, and tan
-1
?
To find the lengths of sides
To find the measure of angles
6
Which equation is correct?
tan(35°)=x/5
cos(B) = x/5
sin(35°)=x/5
cos(35°)=x/5
7
Which of the following are true?
I have asked all of my questions
If I don't do as well as I expect, I will do test corrections
This test does not reflect on my worth as a person
I'm going to do great on this test
8
The value of sin(\frac{12}{13}) is .8324
False
True
9
What is the tangent of angle A?
13/12
5/12
5/13
12/13
10
When do you use sin, cos, and tan?
To find the measure of angles
To find the lengths of sides
11
Which function is opposite/hypotenuse?
Tangent
Sine
Cosine
IDK, but I'm going to put that fun saying on a card. What was it again?
12
What are the solutions to (x+2)(x-4)=0?
x = 2 and -4
x = -2 and 4
x = -2
x = 2 and 4
13
Which function is adjacent/hypotenuse?
Cosine
Sine
Tangent
14
Which function is opposite/adjacent?
Sine
Cosine
Tangent
15
Factor x
2
+5x+6
(x+6)(x-1)
(x+6)(x+1)
(x+3)(x+2)
(x-3)(x+2)
16
What is the tangent of angle B?
5/12
12/5
12/13
12/13
17
What equation can you use to find ∠B?
32+42=∠B2
I feel like ∠B should decide for itself and not conform to the rules
180-90-35=∠B
tan-1\frac{4}{3} = ∠B
18
What is the sine of angle B?
12/5
12/13
13/12
5/12
