ABXC is a right triangle where mzXBC-90°, mzCXB-60°, and XB-5. Determine the length
of each side. Leave your answer as an exact answer.
1. Draw the triangle and label the given parts
2. Identify side types:
30-60-90 has hypotenuse, short, long
45-45-90 has hypotenuse, leg, leg
3. Write the formulas for the special right triangle. Plug in your values and solve.
To enter a square root answer, type the number outside and the number inside using the two
boxes provided. For example, 7√2 would look like 7
Length
Side
CB (long)
XB (hypotenuse)
The the length of each side of the triangle are: 5 units, 8.7 units and 10 units respective
What is a triangle?A triangle is a polygon with three sides, three angles, three vertices and sum of angles equal to 180 degrees
From the triangle, Using the trigonometric ratio of sine
Sin C = opposite/Hypothenuse
Sin30 = 5/H
Making h the subject of the relation we have
h= 5/sin30
h=5/0.5
Therefore the value of h=10 units
To find the third side use Pythagoras theorem
10² = 5²+p²
100-25 = p²
75 = p²
Taking the square of both sides
p=√75
p=8.7 units

There is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 of the same colour?
PLZ answer fast urgant help needed!
Answer:
0.5041 = 50.41% probability of getting 2 of the same colour
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is the probability of getting 2 of the same colour?
Both blue or both red
Since they are replaced, we have, in each trial:
6 blue from a set of 6 + 5 = 11
5 red from a set of 6 + 5 = 11
Probability of both blue:
Each with 6/11 probability. So
\(P = (\frac{6}{11})^2 = \frac{36}{121}\)
Probability of both red:
Each with 5/11 probability. So
\(P = (\frac{5}{11})^2 = \frac{25}{121}\)
Total:
\(p = \frac{36}{121} + \frac{25}{121} = \frac{61}{121} = 0.5041\)
0.5041 = 50.41% probability of getting 2 of the same colour
A copper plate is in the shape of an isosceles triangle with a base of 34 inches. The perimeter of the plate is 110 inches. How long is each of the equal sides of the plate
Answer:
An isosceles triangle has 2 equal sides. If the perimeter is 110 inches, and your base is 34 inches, subtract the base from the total perimeter. 110-34= 76. If 2 sides have to be equal, the total length of the 2 sides is 76 inches, divide the 2 lengths by 2 to get the measure of each side individually. 76÷2=38.
Hence, your answer is each of the equal sides of the plate equals 38 inches.

What is the image of the point (-5, 4) after a rotation of 270° counterclockwise
about the origin?
Answer:
(4, 5)
Step-by-step explanation:
this is the same as a 90° rotation clockwise.
with the coordinates of (-5, 4) we start in the top left quadrant (x values are negative, y values are positive).
and we end up in the top right quadrant (x and y values are positive).
the line from the origin to the point is perpendicular (90° angle) to the line of the origin to the original point, as we just rotated by 90° or 270°.
that means the rules for the slope of perpendicular lines apply :
x and y coordinate differences trade places, and the sign of their ratio is flipped.
luckily, because the origin is the reference point for both lines, the point coordinates are automatically the coordinate differences to (0, 0).
and because we need to get 2 positive coordinates, that means
(-5, 4) turns into (4, 5)
as the alternative (-4, -5) would be in the bottom left quadrant.
14 points! PLEASE HELP!!!
Step-by-step explanation:
I just did in the other posting. how often did you post it ?
this is a trick question. the triangle at the top is not an isoceles triangle.
we use Pythagoras for an the steps.
so, the left part of the baseline (split by the height) is calculated by
12² = 10² + part²
144 = 100 + part²
part = sqrt(44) = 6.633249581... ft
the other part is then
20 - 6.633249581... = 13.36675042... ft
and the second leg of the large triangle is
leg² = 10² + 13.36675042...² = 278.6700168...
leg = 16.69341238... ft
P = 12 + 16.69341238... + 8 + 8 + 20 = 64.69341238... ft ≈
≈ 64.69 ft

along C.
A parametrization of path C is x= 4t and y = 8t
Line segments on nearly trivial to parametrize. It is often it easiest to do in interval t∈ [0,1]
Then we just need to think about what we need to add to each first coordinate to get the second
Since, 0+ 4 = 4 and 0+ 8 = 8
So, parametrization is
=> x = 4t
y = 6t
(b) To evalute the line integral, we have to derivate parametrize
dx/dt = 4
dy/dt = 8
So, the differential line element is
\(ds = \sqrt{(\frac{dx}{dt})^2 + (\frac{dy}{dt})^2}\)
=> √(4)²+(8)²
=> 4√5
Integrating ,
\(\int\limits_{c} {x^2 + y^2} \, ds\\ = \int\limits^1_0 {(4t)^2 + (8t)^2 } 4\sqrt{5} \,dt\\=4\sqrt{5} [\frac{80}{3} t^3]^{1}_{0}\\\)

Solve the equation. -5(-4+2n)=-10(n-2)
Answer:
0 = 0 means that there are infinite solutions.
Step-by-step explanation:
Equation is -5(-4+2n)=-10(n-2)
1. Distribute the -5 and -10
20 -10n = -10n + 20
2. Subtract 20 from one side to the other to get only 1 variable on 1 side.
-10n = -10n
3. divide -10 to separate the variable from the constant.
n = n
This means there are infinite solutions.
