First of all, a pair of angles that are complementary means that they add up to 90 degrees. In this case, angle b + 63 degree = 90 degree (because they are complementary), which mean angle b = 90 - 63 = 27 degree.
Answer: 27°
Step-by-step explanation:
Hello.
Complementary angles add up to 90°
Therefore,
63° + ? = 90°
Now we can subtract!
90° - 63° = 27°
Hope this helps and have a nice day :)

How to determine the length of the segment AB
In this problem we have two similar triangles and we need first to determine the lengths of segments AC and BC and then subtract the length of the latter from the length of the former, that is:
AC/BC = CE/CD
AC/2 = 15/5
AC = 6
AB = AC - BC
AB = 6 - 2

Determine the area of the figure.
Answers
The area of the trapezoid is x+11 cm.
Given a trapezoid has one side of (x+6) cm, the other side is 5 cm, and the height is 2 cm.
A two-dimensional quadrilateral consisting of the sum of non-adjacent parallel sides and a suitable non-parallel side is denoted as a trapezoid.
Now we will use the formula to find the area of a trapezoid
Area = 1/2 × (base 1 + base 2) × height
Here base 1 = (x+6) cm, base 2 = 5cm and height = 2cm
Substituting the values into the formula, we get
Area = 1/2 × (x+6+5) × 2
Area = 1/2 × (x+11) × 2
Area = x+11
Thus, the area of the given figure when one side is x+6, the other side is 5 cm and the height is 2 cm is x+11 cm.

Step-by-step explanation:
Given functions:f(x) = 4x² - 6g(x) = x² - 4x - 8Solution:Subtract both functions
(f-g)(x) = 4x² - 6 - (x² - 4x - 8)
(f-g)(x) = 4x² - 6 - x² + 4x - 8
Combine like terms
(f-g)(x) = 4x² - x² + 4x - 6 - 8
(f-g)(x) = 3x² + 4x - 14

To find : (f-g)(x)
(f-g)(x)=f(x)-g(x)(f−g)(x)=f(x)−g(x)
(4x^2-6)-(x^2-4x-8)
Using Distributive property:-

4x^2-x^2+4x+8-6

Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.
A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.
The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.
The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.

x and y are numbers between 50 and 100. Both x and y have the same digit but in a different order. the two numbers add up to 187 all their digits add up to 34. find x and y.
Answers
By solving a system of equations, we see that:
x = 89 and y = 98.
How to find the two numbers?
First, we can write:
x = a*10 + b
y = b*10 + c
Where a, b, and c are single digit numbers. You can see that b is on both numbers because we know that the numbers share a digit, but on different order.
We also know that:
x + y = 187
a + b + b + c = 34
I we rewrite the first equation, we get:
(a*10 + b) + (b*10 + c) = 187
10a + 11b + c = 187
Then we have two equations:
a + 2b + c = 34
10a + 11b + c = 187
In both equations we can isolate c:
34 -2b -a = c
10a + 11b - 187 = c
Now we have:
-a - 2b + 34 = -10a - 11b + 187
Solving that, we get:
9a + 9b = 153
a + b = 153/9 = 17
Then a and b add up to 17, we can take:
a = 8
b = 9
And:
c = -a - 2b + 34 = -8 - 9 - 9 + 34 = 8
Then the numbers are:
x = 89
y = 98

If the function y = sinx is transformed to y = 3 sine (two-thirds x), how do the amplitude and period change?
Answers
Change in Amplitude is 2

Transforming sin(x) to [tex]3sin(\frac{2x}{3})[/tex]
y = a(sin(bx+c)) + d

Amplitude of sin(x) =1
Period of sin(x) = 2π
Amplitude of 3sin([tex]\frac{2x}{3}[/tex]) = 3
Period of 3sin([tex]\frac{2x}{3}[/tex]) = [tex]\frac{2}{\frac{2}{3}}[/tex]*π = 3π

Answers
Answer:
Option 1
Step-by-step explanation:
Hello!
We can see that the base price for a canoe is $12, as you have to spend the $12 to get the canoe.
You also have to spend $5 per hour in the canoe, which is why "t" is being multiplied by 5.
We can also look at this graphically.
The x-axis is the number of hours, while the y-axis is the price. When x is 0 (no hours on canoe), you can see that the price is $12. But as it increases by 1 hour, the price increases by $5.

The product of 8 and the sum of 4 and a number is 112. What is the number?
Which equation could be used to solve for the number?
8 + 4n = 112
O 8 x 4 + n = 112
8(4 + n) = 112
Answers
Answer:
8(4 + n) = 112Step-by-step explanation:
Let's start by reading the problem since it maybe is a bit confusing at first.
The product of 8
Now we know that it starts with 8 multiplied by another number. We do not know that number yet, so let's put 8 * () and fill in the parentheses later.
So far, our equation is:
8()
.. And the sum of 4 and a number
So, 4 + n
We can enter that into our equation
8(4+n)
The next line says "..Is 112"
So, the solution to our equation is 112
Our equation becomes:
8(4+n)=112
