can someone please explain this and how to do these types of problems??!?! im so confused and i dont know how to do them right
Answer:
28/53
Step-by-step explanation:
We need the cos of Q
therefore we'll use CAH (in SOH, CAH, TOA)
where CAH means
cos(angle)=adj/hyp
the side that adjacent to Q is 28
and the hypotonous (the oppsoite to the right angle) is 53
therefore cos(q)=28/53

How many blue pens were there to start with?
Answer:
180 blue 70 red
Step-by-step explanation:
b= blue r = red
b+r = 250
r = (250-b)
If 40% is removed the rest is 60%
If the 70% is removed the rest is 30%
0.6b + 0.3(250-b) = 129
0.6b + 75 - 0.3b = 129
0.3b = 54
divide by 0.3
b = 180
250-180 = 70
60% 0f 180 = 108
30% of 70 = 21
108 +21 = 129
In ΔUVW, the measure of ∠W=90°, VW = 32 feet, and WU = 78 feet. Find the measure of ∠V to the nearest degree.
Answer: [tex]67.68^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]\angle W=90^{\circ}[/tex]
[tex]VW=32\ ft[/tex]
[tex]WU=78\ ft[/tex]
from the figure, we can write
[tex]\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}[/tex]

3.) In triangle RST, RS = 4, ST = 5, and RT = 6. Which angle is largest?
Hint draw a picture!
A)
B)
C)
D) Cannot be determined
Answer:
So If you start with sinØ = .5
your calculator is programmed to always give the closest angle to 0, and that would be 30°
You probably used the cosine law to find the first angle. A suggestion is to always find the largest angle first. If that happens to be an obtuse angle, your calculator will find the correct angle.
Of course there can only be one obtuse angle in a triangle, so using the sine law for your second angle does not result in any problems
notice that in your solution 78 and 102 add up to 180 , and sin 78 = sin(180-78) = sin 102
I would have found angle S first, the largest angle always opposite the largest side.
7^2 = 5^2 + 4^2 - 2(5)(4)cosØ
40cosØ = -8
cosØ = -8/40 = -1/5
Ø = 101.537°
Now you can use the sine law and you will find the correct other angles.

If m <1 = 115° and the m < 8 = 105°, what is the measure of angle 5?
Answer:
measure of angle 5 = 75 degrees
Step-by-step explanation:
given measure of angle 8 = 105 degrees,
angle 8 and angle 5 are in a linear pair so,
(the sum of angles in a linear pair is 180 degrees)
therefore, angle 8 + angle 5 = 180 degrees
therefore,. 105 + angle 5 = 180 degrees
angle 5 = 180 - 105
angle 5 = 75 degrees

the population of a city is 10,000 people. A researcher wants to estimate how many people own a car and how many don't. The researcher surveys a random sample of 240 and records and these results. 180 people do own a car and 60 people don't. estimate the number of people that do own a car and don't, round to the nearest 500
Answer:
7380 people have cars and 2460 people dont so rounded to the nearest 500 i would say it is 1000

3) Six teams are playing in a baseball tournament. In how many ways can the teams be crowned champion and
runner-up?
Answer:
15ways
Step-by-step explanation:
This question bothers combination
Combination has to do with selection
Given
Total number of teams = 6
champion and runner up = 2
number of ways is expressed as 6C2
6C2 = 6!/(6-2)!2!
6C2 = 6!/4!2!
6C2 = 6*5*4!/4!*2
6c2 = 30/2
6C2 = 15
Hence the number of ways they can be selected is 15ways
The figure shows a large triangle divided into two smaller triangles what is the value of x in the figure
Answer:
40
Step-by-step explanation:
Find the other missing angle, which is supplementary to 100 first.
Supplementary angels are a sum of 180
The missing angle is 180-100 = 80
Now use that to find missing angle x
All angles in the triangle have a sum of 180
180 = 60+80+x
180-60-80=x
40 = x

Have a good day :)
Step-by-step explanation:
Given :
12 , -1 , -14 ....And we need to find the next two terms of the sequence. Firstly let's find out the common difference.
[tex]:\implies[/tex] CD = -12-1 = -13
Next two terms :-
[tex]:\implies[/tex] Next terms = -53 , -66
Hence the next terms are -53 & -66 .
