5 frisbees and 3 volleyballs cost $36 the cost of 2 frisbees and 7 volleyballs is $18 which of the following systems could be used to calculate the cost of one frisbee and one volleyball
Answer:
C
Step-by-step explanation:
I believe it is C because each letter is simply standing for the variable you are missing. So basically, 5 frisbees * the cost of frisbees added to 3 volleyballs * the cost of volleyballs will create the total of $36 --> 5f + 3v = $36. This applies to the 2 and 7 as well, I hope this helps :)

Find all possible values of x for which these two triangles are similar.
Answer:
I see no solution.
Step-by-step explanation:
The sum of the angles of a triangle is 180°
Given
x+ x + 10 +y = 180. and
2x -50 + 50 + y = 180
y represents the angles with no value indicated.
Simplifying:
2x +y +10 = 180
2x + y = 180
This looks like a no solution system.
If I'm missing something, I hope someone else can explain it.
The two triangles are similar when two angles of the triangle are equal.
The possible value of x which the two triangles are similar is x = 60°
Reasons:
Required;
To find the values of x for which the two triangles are similar
Method:
Given that two angles of the triangle are specified, the triangles can be
similar for only one value of x.
Solution:
The two triangles are similar when we have;
x + 10° = 2·x - 50°
Which gives;
2·x - x = 50° + 10° = 60°
x = 60°
Checking gives;
x + 10° = 2·x - 50° = 70°
Two angles of the first triangle are;
70° and 60°
The third angle of the first triangle is (180° - (70° + 50°)) = 60°
The three angles of the first triangle are therefore; 70°, 60° and 50°.
Two angles of the second triangle are;
70° and 50°
The third angle of the second triangle is (180° - (70° + 50°)) = 60°
The three angles of the second triangle are therefore; 70°, 60° and 50°
Therefore, the two triangles are similar by AAA similarity.
The two triangles are similar when, x = 60°When x = 50°, we have;
x + 10° gives;
50° + 10° = 60°
∴ ∠(x + 10°) = 60°
The two angles of the first triangle are; 60° and 50°
The third angle on the second triangle is 180° - (60° + 50°) = 70°
On the second triangle, we have;
2·x - 50° gives;
2 × 50° - 50° = 50°
∴∠(2·x - 50°) = 50°
Therefore, the two angles of the second triangle are; 50° and 50°
The third angle on the second triangle is 180° - (50° + 50°) = 80°
Therefore, the two triangles are not similar when x = 50°
Similarly, the two triangles are not similar when x + 10° = 50°
Therefore;
The possible value of x which the two triangles are similar is x = 60°

Explanation:
Consider the attached diagram.
Arc RB is centered at O and has a radius of 1. Angle ROD is designated angle α. It is duplicated as angle DOB, meaning that OD is the perpendicular bisector of chord RB. Triangles DFB and RGD are congruent (by HA). They are similar to triangle RDO by AA similarity.
Now, we can use the definitions of sine and cosine to find some segment lengths. Since the circle is of radius 1, the length RD is sin(α). Then, in triangle RGD, the length DG is sin(α)·cos(α). As we said, BF is congruent to DG, so the length BH is 2·sin(α)·cos(α). Again, by the definition of sine, BH = sin(2α). So, we have ...
sin(2α) = 2·sin(α)·cos(α) . . . . the desired relationship

How do you solve this?
Answer:
In general, we already know how to solve problems in a right triangle using the concept of trigonometry. Meanwhile, as we also know that the type of triangle is not only a right triangle, but there are isosceles, equilateral, or even random triangles. The question is how to solve the problems that exist in these triangles It is known that there is an arbitrary triangle with sides a, b, and c. The angle formed in front of side a is called angle α, the angle formed in front of side b is called angle β, and the angle formed in front of side c is called angle γ = 5

Answer: 32 sq.cm
Step-by-step explanation:
If you think of it as there being 2 squares instead of 1, you can think well since the whole one side of the rectangle is 8cm and the half side is 4 then that must mean that the other square that you just divided up must be 3 by 4 so then you can multiply those and get 12 and you do the same for the other one which would be 4 by 5 and when you multiply those you will get 20 and when added you get 32.

Purchased Amount Paid Egg Plant 3 lb $ 21 Beetroot 5 lb $ 28 Which vegetable costs more per pound?
Answer:
eggplant cost more/pound.
Step-by-step explanation:
ep= 7$/pound
br= 5.6$/pound
That the Egg Plant costs more.
My reasoning for this is because if you do 21 divided by 3 it equals 7 which means each pound of Egg Plant is $7. But 28 divided by 5 is 5.60. Which means, Beetroot is $5.60 per pound! So, beetroot is less than the Egg Plant!
