Answer:
Solution given:
Cos -θ:[tex]\frac{\sqrt{3}}{4}[/tex]
since cos -θ=Cos θ
Cos θ :[tex] \frac{\sqrt{3}}{4} [/tex]
[tex]\frac{\sqrt{b}}{h} [/tex]=:[tex] \frac{\sqrt{3}}{4} [/tex]
b=[tex]\sqrt{3} [/tex]
h=4
p=[tex] \sqrt{4²-(\sqrt{3})²} [/tex]=[tex] \sqrt{13}[/tex]
So
Sin θ=[tex]\frac{p}{h} [/tex]=[tex]\frac{\sqrt{13}}{4} [/tex]
So third one is a required answer.

A jar contains 5 blue marbles, 1 yellow marble, and 4 green marbles. What is the probability of randomly choosing a yellow marble, replacing it , and then choosing a yellow marble again
Answers
Answer:
1/100
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
the probability = (number of yellow marbles / total number of marbles) x (number of yellow marbles / total number of marbles)
total number of marbles = 1 + 5 + 4 = 10
(1/10) x (1 / 10) = 1 /100

At the amusement park, Janine bought a bottle of water for $2. She also bought game tickets for $0.50 each. Janine spent a total of $15.
Which of the following equations can be used to find the number of game tickets, g. Janine bought?
O 0.509 + 2 = 15
O2g +0.50 = 15
O 0.50g - 2 = 15
O 2g -0.50 = 15
Answers
Answer:
15 = 2 + 0.5g
Total number of ticket purchase by Janine = 26
Step-by-step explanation:
Given:
Cost of water bottle = $2
Cost of each ticket = $0.50
Total amount spend by Janine = $15
Find:
Equation
Computation:
Assume;
Total number of ticket purchase by Janine = g
Total amount spend by Janine = Cost of water bottle + (Cost of each ticket)(Total number of ticket purchase by Janine)
15 = 2 + (0.5)(g)
15 = 2 + 0.5g
0.5g = 13
g = 13 / 0.5
Total number of ticket purchase by Janine = 26
A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?
Answers
Answer:
Right, I am an idiot so i might be wrong
Step-by-step explanation:
Every triangle has three angles which sum to 180 degrees.
There are three types of triangles based on the measures of its angles.
Right Triangle - Has one 90 degree angle
Acute Triangle - All angles less than 90 degrees
Obtuse Triangle - One angle greater than 90 degrees
In this example we are given 2 angles and must find the measure of the 3rd.
a + 56 + 34 = 180
a + 90 = 180
a = 90
Therefore, it is a Right Triangle.
Pleaseeeeeeeeeeeeee !!
Answers
Answer:
90
Step-by-step explanation:
all angels equal 180 so add the two you have then subtract 180 with the answer you got

Which are necessary conditions to apply the SAS Triangle Congruence Theorem? Select all that apply
Answers
Answer:
A.) Two sides and the included angle of a triangle are congruent to the CP of another triangle
Step-by-step explanation:
So, SAS. The Side-Angle-Side congruence postulate.
To have SAS congruence, 2 adjacent sides of a triangle need to be congruent to another triangle's adjacent sides, AND the angles between (re: included angles) them need to be congruent as well.
The answer most similar to that would be A!

How do you find zeros of a quadratic function?
Answers
Answer:
You find the zeros of a quadratic functions by factoring the function. And once you have factored the function you take the factors and flip the signs. For example, you have the factors (x-4) and (x+3).
Drop the parentheses and make x equal to zero.
x - 4 = 0 x - 3 = 0
Solve it like a one step equation.
x - 4 = 0 x - 3 = 0
+ 4 +4 +3 +3
= 4 = 3
Then turn into coordinates.
x y x y
(4,0) (3,0)
Note that the zero's are the x-intercepts. I labeled x above the first part of the coordinate to show where the x-intercepts should and the same with the y.

Answer:
∠P = 21
Step-by-step explanation:
angle P is an inscribed angle and arc RQ is the arc it intercepts
The measure of an inscribed angle is equal to half the measure of the arc it intercepts.
Hence, ∠P = [tex]\frac{1}{2}[/tex] ( arc RQ )
So if arc RQ = 42°
Then ∠P = 42/2
42 / 2 = 21
Hence, ∠P = 21°
