Answer:
Yes, they are similar triangles
Step-by-step explanation:
If you make a proportion using vertical side/horizontal side
[tex]\frac{4}{10} =\frac{12}{30} \\[/tex]
If you multiply 4/10 by 3/3 you will get 12/30, so the triangles are similar.

The value of x is 7.5.
DilationDilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
The smaller triangle was dilated to form the larger triangle.
A smaller triangle has side lengths of 5, 13, 12. A larger triangle has side lengths of x, blank, 18.
To findThe value of x.
How to find the value of x?We know the formula.
Side of a large triangle = Dilation x Side of a small triangle
Then we have,
18 = Dilation x 12
Dilation = 1.5
So the blank side will be
Blank side = 1.5 x 13
Blank side = 19.5
And x will be
x = 1.5 × 5
x = 7.5
Thus, the value of x is 7.5.

Step-by-step explanation:
3/10 converted to a decimal is .3 (30%), and since it says he swan MORE then that we can assume they mean 80 + 30% more.

Advanced Trigonometry, pls help me answer this!
======================================================
Explanation:
We have this given info
side a = 5side c = 6angle C = 40Let's apply the law of sines to find angle A
sin(A)/a = sin(C)/c
sin(A)/5 = sin(40)/6
sin(A) = 5*sin(40)/6
sin(A) = 0.535656
A = [tex]\sin^{-1}[/tex](0.535656) or A = 180-[tex]\sin^{-1}[/tex](0.535656)
A = 32.388411 or A = 147.611589
There are two possibilities here we need to check.
If you were to try A = 147.611589 along with C = 40, then A+B+C = 180 solves to B = -7.6116 approximately. This isn't valid because the angles cannot be negative. So we rule out the case that A = 147.611589
If we tried A = 32.388411 and C = 40, then we'd get B = 107.611589 which is a valid angle.
------------------
The last step is to use the SAS triangle area formula to get...
area = 0.5*side1*side2*sin(angle)
area = 0.5*a*c*sin(B)
area = 0.5*5*6*sin(107.611589)
area = 14.296942
This rounds to 14.3 when rounding to 3 significant figures.

a support wire to a newly planted tree makes a 32° angle with the ground.
determine the angle made by the wire at the point of contact to the tree by finding the complement of 32°
Answer:
58°
Step-by-step explanation:
Since the angle made by wire with ground and at the point of contact to the tree are complementary.
So,
Required angle = 90° - measure of the angle formed by wire with ground
Required angle = 90° - 32° = 58°

The length of the instrument storage closet will be 15ft
Dimension of an objectGiven the dimension of Mr. Miller’s band room is 50 ft wide and 75 ft long. In order to get an instrument storage closet that has the same proportions of length and width but is smaller, we can multiply the width and the length by a scale factor.
Using the scale factor of 1/5, the new dimension will be expressed as:

what is the greatest common factor of 32a and 48b
32=16x2=2x2x2x2x2=2^5
48=24*2=6x4x2=2x3x2x2x2
Pick the highest number that occurs. In this case it is 2. Now we have to see how many times it appears in both. It appears 5 times in 32 and 4 times in 48. 4 is the highest number of times it appears in the numbers so:
2^4=2x2x2x2=16
The Greatest Common Factor (GCF) of 32 and 48 is 16.

Answer: 1st one : degree = 5; number of terms = 3
2nd one: degree = 6; number of terms = 4
3rd one: degree = 4; number of terms = 2
Step-by-step explanation: First you have to simplify everything.
So for the first one you would get 14x^5 -30x^4 + 2x^3; After that you just say that the degree is 5, and number of terms is 3. For the second one you do the same thing; simplify and then find the degree and number of terms. If your confused on how to simplify then look at the work that I've showed below (my work) And if your confused on how to find the degree, it's just what term has the highest power, to be more clear lets say we have x^3 + x^4*y^7. We have 2 terms, and the degree of the 1st is 3, and the degree of the second term is 11. Meaning the degree of the polynomial is 11 (the larger one) If your confused on how to find the amount of terms, then it's just counting them, they're divided by subtraction and addition.
