The length of r, to the nearest 10th of an inch, is 2.4 inches.
What is the sin angle theorem?The relationship between the sides and angles of non-right (oblique) triangles is defined by the Law of Sines. Simply put, it states that the ratio of the length of a triangle's side to the sine of the angle opposite that side is the same for all triangle sides and angles.
Given that in ΔQRS, s = 5.2 inches, ∠S=129° and ∠Q=30°. The value of side r will be calculated by using the sin angle theorem.
The value of r is,
r / sin21 = s / sin129
r = 5.2 x ( sin21/sin129)
r = 5.2 x 0.46
r = 2.4 inch

Solve for angle B, then side a. Round to the nearest tenth.
Answer:
Angle B: 28 degrees
Side a: 27.6
Step-by-step explanation:
Angle B:
180-112-40=28
Side a:
sin 28/14 = sin 112/a
a = sin 112(14)/sin 28
a = 27.6
Which expression is not equal to 1?
sin θ csc θ
cos θ sec θ
tan θ cot θ
sin θ cos θ
Answer:
sin θcos θ
hope it is helpful to you
Answer:
sin A cos A
Step-by-step explanation:
[ I don't know to type angle theta here so assume A as theta]
As , sin A= p/ h
cos A= b/ h
so,
sinA cosA = p/ h × b/h
= pb/ h^2 ( which is not equal to 1 )
Tip; you can easily verify other relations expressing trigonometric ratios in terms of p,b & h and further simplifying..
In the following triangle, angle A measures 49° and angle C measures
62.
Answer:
The measure of angle B is 69°.
Step-by-step explanation:
All angles of the triangle should add up to 180°, so you add angle A and angle C together, and then subtract that number from 180.
49 + 62 = 111
180 - 111 = 69
69°

Find the area of the largest square contained by a circle of radius r = 1cm. Explain your answer and justify that it is correct. Hint: Use the pythagorean theorem.
Answer:
2 square cm
Step-by-step explanation:
Given :
A square is inscribed in a circle whose radius is r = 1 cm
Therefore, the diameter of the circle is 2 r = 2 x 1
= 2 cm.
So the diagonal of the square is 2r.
Using the Pythagoras theorem, we find each of the side of the triangle is [tex]$r \sqrt 2$[/tex].
Therefore, the area of the square is given by [tex]$\text{(side)}^2$[/tex]
= [tex]$(r\sqrt 2)^2$[/tex]
[tex]$= 2 r^2$[/tex]
[tex]$= 2 (1)^2$[/tex]
[tex]$=2 \ cm^2$[/tex]
Hence the area of the largest square that is contained by a circle of radius 1 cm is 2 cm square.

A local paintball facility charges $30 to play plus $0.25 per paintball pellet used. Elijah plans on playing paintball and has $60 to spend at the facility. Which equation can be used to determine p, the number of paintball pellets he can use if he spends exactly $60?
A. 30 + 0.25p = 60
B. 30 + 0.25 = 60p
C. 30p + 0.25 = 60
D. 30 − 0.25p = 60
Step-by-step explanation:
Hello! I believe the answer is A. 30+0.25p=60.
Elijah has to pay a facility charge which is 30$. So we can go ahead and write that down! He has 60$ to spend, but he has to pay $0.25 per paintball. So we write that as 30+0.25p=60!! If you have any questions comment doen below!

6x+?= 10x
6x−?= 2x
6x+?= 2x
6x−?= 10x
6x+?=- 10x
6x−?= x
6x+?= 0
6x−?= 6
6x+?= 10
6x−?= 4x - 10
Answer:
x=0
Step-by-step explanation:
Let's solve your equation step-by-step.
6x+x=10x
Step 1: Simplify both sides of the equation.
6x+x=10x
(6x+x)=10x(Combine Like Terms)
7x=10x
7x=10x
Step 2: Subtract 10x from both sides.
7x−10x=10x−10x
−3x=0
Step 3: Divide both sides by -3.
−3x/−3 = 0/−3
x=0

Step-by-step explanation:
[tex] \frac{3x}{8} - \frac{x + 5}{4} [/tex]
The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.
Thus:
[tex] \frac{1(3x) - 2(x + 5)}{8} [/tex]
[tex] \frac{3x - 2x - 10}{8} [/tex]

Answer:
x = 30Step-by-step explanation:
According to figure,
54° + 3x+36° = 180° [Linear pair]
=> 3x + 90 = 180
=> 3x = 180 - 90
=> 3x = 90
[tex] = > x = \frac{90}{3} [/tex]
=> x = 30 (Ans)
Answer:
x=30
Step-by-step explanation:
cuz that line is 180 degrees and using algebra you can subtract 54 from both sides and get 126 then u have to subtract the 36 from both side to geth 90 and then divide the 3x to get x by itself which would leave u with 30 so x=30
