what does this mean when a rhombus is split into 2 triangles ; what's the formula to find the value of x? also it's about polygons
Answers
Answer/Step-by-step explanation:
The rhombus when split into two triangles will give us two equilateral triangles that are congruent to each other.
Therefore:
The two bases of both triangles will have equal angle measures of 4x + 5 each and a third angle measure of 8x - 6.
✅Formula to find the value of x:
(8x - 6) + 2(4x + 5) = 180° (sum of triangle)
8x - 6 + 8x + 10 = 180
8x + 8x - 6 + 10 = 180
16x + 4 = 180
16x + 4 - 4 = 180 - 4
16x = 176
16x/16 = 176/16
x = 11

2x+20-(5X3)=30. Solve for x.
Answers
Answer:
25/2
Step-by-step explanation:
Use order of operations to solve in the bracket.
2x + 20 - ( 5X3) = 30
2x + 20 - (15) = 30
Now open the brackets.
2x + 20 - 15 = 30
2x + 5 = 30
Subtract both sides by 5
2x = 25
Divide both sides by 2.

Answer:
Step-by-step explanation:
Perimeter of the triangular base = 10 + 10 + 16
= 36 ft
Height of the prism = 15 ft
Base area = Area of the triangle
= [tex]\frac{1}{2}(\text{Base})(\text{Height}})[/tex]
= [tex]\frac{1}{2}(16)(6)[/tex]
= 48 square ft
Surface area of the triangular prism = 2(base area) + (perimeter × height)
= 2(48) + 36(15)
= 96 + 540

[tex]P(3) = 0.3397[/tex]
Step-by-step explanation:
The given details represent binomial distribution. So, we have:
[tex]n = 5[/tex]
[tex]p = 64\% = 0.64[/tex]
Required
Calculate P(3)
This is calculated using:
[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]
This gives:
[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]
[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]
[tex]P(3) = 0.3397[/tex]
(2,2) and (2,-2) slope?
Answers
Answer:
Undefined.
Step-by-step explanation:
Slope is equal to the change in y over the change is x, or rise over run.
[tex]m=\frac{change in y }{ change in x}[/tex]
The change in x is equal to the difference in x-coordinates, and the chnage in y is equal to the difference in y-coordinates.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Substitute in the values of x and y into the equation to find the slope.
[tex]m= \frac{-2-(2)}{2-(2)}[/tex]
Simplify it. since -2-(2) and 2-(2) = nothing, the Slope is Undefined.
Hence, the slope is Undefined.

You buy halibut at $25 per pound.one portion of seared halibut requires 6 ounces of halibut.how much does the halibut for one portion cost ?
Answers
Answer:
$9.38
Step-by-step explanation:
halibut is measured in pounds and a portion is measured in ounces
in order to determine the cost, the two units have to be comparable. So, ounces have to be converted to pounds
1 ounce = 0.0625 pounds
6 ounces = 0.0625 x 6 = 0.375 pounds
0.375 pounds would cost 0.375 pounds x 25 pounds = $9.38

They have a rectangle ABCD as shown below, where AB = 24cm BC = 10cm and AE = 13cm
A. Calculate the volume of the rectangle ABCD
B. Calculate the circumference of the BCD triangle
C. Calculate the circumference of the BEC triangle
D. Calculate the circumference of the DEC triangle
Answers
Answer:
A. Area of ABCD = 240 [tex]cm^{2}[/tex]
B. 60 cm
C. 36 cm
D. 50 cm
Step-by-step explanation:
Given: AB = 24cm BC = 10cm and AE = 13cm.
A. Since a rectangle is a 2 dimensional figure, it has no volume but area.
So that,
the area of the rectangle ABCD = length x width
= 24 x 10
= 240 [tex]cm^{2}[/tex]
B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.
[tex]BD^{2}[/tex] = [tex]BC^{2}[/tex] + [tex]DC^{2}[/tex]
= [tex]10^{2}[/tex] + [tex]24^{2}[/tex]
= 676
BD = [tex]\sqrt{676}[/tex]
= 26
BD = 26 cm
so that,
the circumference of BCD = 10 + 24 + 26
= 60 cm
C. To calculate the circumference of the BEC triangle,
AC = 26 cm, AE = 13 cm
CE = 26 - 13
= 13 cm
CE = 13 cm
The circumference of the BEC triangle = 13 + 13 + 10
= 36 cm
D. The circumference of the DEC triangle = 13 + 13 + 24
= 50 cm
