Can someone explain the process of getting to Angle A? I know the answer is 44.1 but I need to show my work so can someone show me the process of getting the answer and please explain! Thank you!!
Answers
Answer:
Step-by-step explanation:
First you have to calculate CB in order to use sin law to calculate ∠A
CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]
CB=12.8(correct to nearest tenth)
After that, use sin law to calculate ∠A,
[tex]\frac{18.4}{sin90} =\frac{12.8}{sinA}[/tex] or [tex]\frac{sin90}{18.4} =\frac{sinA}{12.8}[/tex]
sinA=0.695...
A=44.079...
=44.1(corrext to the nearest tenth)
Is that clear enough for you?

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?
Answers
Answer: The other point is (17, -6).
Step-by-step explanation:
Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-
[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]
Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).
Let other point be (a,b), then
[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]
hence, the other point is (17, -6).
Does anyone know this if you could help me I would appreciate it
Answers
Answer:
C, B
Step-by-step explanation:
Basically to find the slope you take the rise over run. How many squares does the line go up, over how many does it go left or right. As you can see in the diagram, it goes up 2 squares and goes left 1 square, giving the slope 2/1, which is 2.
The slope of a horizontal line is straight, which means it goes up 0, so automatically your answer is zero, because dividing anything by 0 is 0.

Step-by-step explanation:
Given that,
The cost of a computer = $65,000 + value added tax at 15%
We need to find the amount the computer actually cost the customer.
Total cost = Cost of computer + VAT at 15%
[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]
So, the computer actually cost the customer is $74,750.

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Answers
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

A rectangular parking lot has an area of 1650 yd.² the length of the parking lot is 55 yards what is the width of the parking lot in yards
Answers
Answer:
The width of parking lot is 30 yards.
Step-by-step explanation:
Given that:
Area of rectangular parking lot = 1650 yards square
Length of parking lot = 55 yards
Width of parking lot = x yards
Area of rectangle is given by:
A = Length * Width
1650 = 55x
Dividing both sides by 55
[tex]\frac{55x}{55}=\frac{1650}{55}\\x=30[/tex]
Hence,
The width of parking lot is 30 yards.
