Answer:
24°
Step-by-step explanation:
The sum of all interior angles of a triangle always equal to 180°.
There are two givens in the problem. Set up the equation by equaling 180 to the two given angles and the unknown.
[tex]180 = 102 + 54 + x\\180 = 156 + x\\[/tex]
Isolate x by subtracting 156 to both sides.
[tex]180 - 156 = 156 - 156 + x\\x= 180-156\\x=24\\[/tex]
Complete the matrix that represents a reflection over the x-axis in the coordinate plane.

The price of an item has risen to $387 today. Yesterday it was $180. Find the percentage increase
Answer:
115%
Step-by-step explanation:
Given that,
The initial price of an item = $180
The final price of an item = $387
We need to find the percentage increase. It can be calculated as follows :
[tex]\%=\dfrac{\text{Change in price}}{\text{initial price}}\times 100[/tex]
Put all the values,
[tex]\%=\dfrac{387-180}{180}\times 100\\\\=115\%[/tex]
So, the required percentage increase is 115%.
Convert the polar representation of this complex number into its rectangular form: z=4(cos120 + isin 120)
Please help!!! I will mark brainliest!!!!!!!!
Answer:
The answer is D
Step-by-step explanation:
took the test
The polar expression of a complex number in its rectangular form 4(cos120° + i sin120°) = -2 + 2√3 i.
What is the polar form of a complex number?Let Z = a + ib be a complex number in the cartesian form represented by point P(a, b) in the complex plane then Z = r cos∅ + i r sin∅ =r is called the polar form of a complex number.
We have.
z = 4(cos120° + i sin120°)
z = 4(cos(90 + 30)° + i sin(90 + 30)°)
Using trigonometry
cos (90 + ∅) = -sin ∅ and sin (90 + ∅) = -cos ∅
So, 4( -sin (30)° + i cos (30)°)
= 4 ( -1/2 + i √3/2)
= -4(-1/2) + i 4(√3/2)
= -2 + 2√3 i
Thus, the rectangular form is 4(cos120° + i sin120°) = -2 + 2√3 i.

Answer: y=6x+8
Step-by-step explanation:
slope intercept form: y= mx+b
slope(m)= (y2-y1) / (x2-x1)
using the first two columns, we get:
(14-8)/(1-0) = 6/1= 6
to find b: find the y value where x=0
that gives us b=8
therefore, if we plug in m and b into the slope intercept form, we get
y = 6x + 8
Answer: y=6x+8

Which of the following are examples of irrational numbers? Select all that apply.
V4 + V16
15+ 36
√9+ /24
2.v4
49.81
Answer:
A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction. An irrational number is a number that is NOT rational. It's the complete opposite!
= 2 + 4 = 6 ↔ rational
= 2 * 2 = 4 ↔ rational
= 7 + 9 = 16 ↔ rational

If you have a cube measuring 1 unit on each side, how many of those cubes would fit into a space 2 units by 3 units by 4 units
Given:
Measure of a cube = 1 unit on each side.
Dimensions of a space 2 units by 3 units by 4 units.
To find:
Number of cubes that can be fit into the given space.
Solution:
The volume of cube is:
[tex]V_1=a^3[/tex]
Where, a is the side length of cube.
[tex]V_1=(1)^3[/tex]
[tex]V_1=1[/tex]
So, the volume of the cube is 1 cubic units.
The volume of the cuboid is:
[tex]V_2=l\times b\times h[/tex]
Where, l is length, w is width and h is height.
Putting [tex]l=2,b=3,h=4[/tex], we get
[tex]V_2=2\times 3\times 4[/tex]
[tex]V_2=24[/tex]
So, the volume of the space is 24 cubic units.
We need to divide the volume of the space by the volume of the cube to find the number of cubes that can be fit into the given space.
[tex]n=\dfrac{V_2}{V_1}[/tex]
[tex]n=\dfrac{24}{1}[/tex]
[tex]n=24[/tex]
Therefore, 24 cubes can be fit into the given space.
