Option B
You use sine rule to find the missing angles
Answered by GAUTHMATH
For any triangle ABC, The correct option the given triangle is B. m∠B=47, m∠C=28, b=28.
What is law of sines?For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,
we have, by law of sines,
[tex]\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}[/tex]
Remember that we took,
[tex]\dfrac{\sin(angle)}{\text{length of the side opposite to that angle}}[/tex]
We have been given angle A = 105 degrees and side a = 37, side c = 18.
[tex]\dfrac{sin\angle A}{a} = \dfrac{sin\angle C}{c}\\\\\dfrac{sin\angle 105}{37} = \dfrac{sin\angle C}{18}\\\\sin\angle C = \dfrac{sin\angle 105}{37} \times 18 \\\\sin\angle C = 28[/tex]
By angle sum property;
A + B + C = 180
105 + 28 + B = 180
B = 180 - 133
B = 47
Therefore,
[tex]\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b}\\\\\dfrac{sin\angle 105}{37} = \dfrac{sin\angle 47}{b} \\\\b = 28[/tex]
Hence, the correct option the given triangle is B. m∠B=47, m∠C=28, b=28.

The entrance fee to a local waterpark is $34 per person. At the waterpark, you can rent a raft for $1.50 per hour. Which expression is equivalent to the amount it would cost Leah for h hours in the park if she rented a raft?
Answers
The entrance fee to enter the park is fixed and the amount of hours Leah will spend at the park is a variable.
We need to add the fixed and variable amounts.
34 + h
Because we don’t know how long Leah will spend on the raft we have to multiply h by the rate per hour for a raft.
34 + 1.50h
Therefore, Leah’s cost is 34 + 1.50h
Answer: 34+1.50h
Step-by-step explanation:
Algebraic Equation:
The entrance fee to the waterpark is the intial cost for Leah to get in the park. The amount of hours that Leah will spend at the park is a variable.
You need to add the intial cost and the variable amounts together.
34+h
You put the h in the equation because you don't know how long Leah will spend on the raft. You will be multiply by the rate per hour for a raft.
34+1.50h
Therefore the cost for Leah is 34+1.50.
34 + 1.50h
Therefore, Leah’s cost is 34 + 1.50h.
If the ratio between the radii of two spheres is 3:7, what is the ratio of
their volumes?
A. 27:343
B. 9:49
C. 9:7
D. 21:49
Answers
Answer:
A
Step-by-step explanation:
Ratio of volume is ratio of the radius raised to the power 3.
The ratio of the volume of the spheres is 27 : 343
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
The ratio of the radii of two spheres is 3:7.
Therefore, if the smaller sphere has a radius of 3x, then the larger sphere has a radius of 7x.
The ratio of the volumes of the two spheres is given by:
(Volume of smaller sphere) : (Volume of larger sphere) = (4/3)π(3x)³ : (4/3)π(7x)³
Simplifying the above expression, we get:
(Volume of smaller sphere) : (Volume of larger sphere) = 27 : 343
Hence , the ratio of the volumes of the two spheres is 27 : 343

If two natural numbers are n and (n+3) prove that the differences of their square is an even numbers
Answers
Answer and explanation:
Given two natural numbers n and n+3, we prove that the difference or their squares is even thus:
(n+3)²-(n)²= (n+3)(n+3)-(n)²
=n²+3n+3n+9-n²
=6n+9
Since the value of the difference of square of the natural numbers n and n+3 is in the form 6n+9, the difference is not an even number.

ΔFED

Answers
Answer:
FED ~ MLF
Step-by-step explanation:
∠L = ∠E
∠F = ∠F
Since both angles are congruent, that would mean all angles are congruent.
If all angles are congruent, then the triangles are always similar no matter the length of the sides.
The complete statement is [tex]\triangle FED\sim \triangle FLM[/tex].
What are the similar triangles?Similar triangles are the triangles that have the same shape, but their sizes may vary.
What is AA or angle angle similarity rule?If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.
What are vertically opposite angles?When two lines intersect each other, then the opposite angles are formed due to intersection are called vertical angles or vertically opposite angles.
According to the given question.
We have two triangles LMF and EDF
In triangles LMF and EFD we have
∠MLF = ∠DEF (given)
Also, ∠MFL = ∠DFE (vertically opposite angles)
Since, we know that " if any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other".
Therefore, by AA similarity criteria triangle FED is similar to FLM.
Hence, the complete statement is [tex]\triangle FED\sim \triangle FLM[/tex].

It cost 2.10 for a gourmet coffee shop to make a small latte.The price of a small latte is 2.94.What is the percent markup on the latte
Answers
Answer:
40%
Step-by-step explanation:
Given that :
Cost of production of small latte = 2.10
Sale price of small latte = 2.94
The Markup = Sale price of small latte - cost of production of small latte
The Markup = 2.94 - 2.10 = 0.84
Percentage Markup = (0.84 / 2.10) * 100%
Percentage Markup = 0.4 * 100% = 40%

Here, we need to know the triangle sum theorem.
The Triangle Sum Theorem states that the sum of the three interior angles in a triangle is always 180°.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
According to the Triangle Sum Theorem:
∠1 + ∠2 + ∠3 = 180
Substitute the angle values
(60) + (50) + (7x) = 180
Combine like terms
110 + 7x = 180
SUbtract 110 on both sides
110 + 7x - 110 = 180 - 110
7x = 70
Divide 7 on both sides
7x / 7 = 70 / 7
x = 10
