d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3

A complex shape made of two rectangles. The bottom rectangle has measurements 3 meters by 4 meters. The top rectangle has measurements 3 meters by 2 meters plus 4 meters plus 2 meters. Side A B is opposite of the side with measurements 2 meters, 4 meters, 2 meters. What is the distance from point A to point B? 8 m What is the perimeter of the shape?
Answers
The length of the side opposite to points A and B is 8 m
The perimeter of the shape is 18 m.
What is the distance from point A to point B?The length of the side opposite to points A and B, is 2 meters and 4 meters and 2 meters.
Length of AB = 4 m + 2 m +2 m = 8 m.
The perimeter of the complex shape by adding the lengths of all its sides;
Perimeter = length of AB + length of BC + length of CD + length of DA
Length of BC = length of the bottom side of the top rectangle = 3m
Length of CD = length of the top side of the top rectangle = 3 m.
Length of DA = length of the bottom side of the bottom rectangle = 4 m.
The perimeter of the complex shape is calculated as follows;
Perimeter = 8 m + 3 m + 3 m + 4 m
Perimeter = 18 m.

A. c^7
B. c^11
C. c^16
D. c^28
E. c^142
PLEASE I WILL LEGIT CRY
Answers
Answer:
B: c^11
Step-by-step explanation:
Separate the equation:
c^14/c^6 + c^3/c^6
c^14-6 + c^3/c^6 = c^8 + c^3/c^6
c^8 + c^3-6
c^8 + c^-3
Turn the -3 positive
The final equation = c^8+c^3
Therefore, c^11 is the correct answer.

Steps:
6cm + 8 cm = 14cm
Answer:
14 cm
Step-by-step explanation:
this is because of the far left side of the shape being 6cm and as well as with the 8 cm from one side of the shape being another component to the origin of the side length, this would give us the equation 6 + 8 with out sum coming out to 14 cm being identified as the right unknown length.

Use 3.14 as an approximation for IT
A 5,024 m
B 2,152 m²
C 1,256 m2
D 628 m²
Answers
Answer: D) 628 m^2
==========================================================
Explanation:
Let's find the area of the full circle first. The radius is 20 meters, since that's half of the diameter 40. So we have r = 20.
We'll use pi = 3.14 as an approximation
A = area of full circle
A = pi*r^2
A = 3.14*20^2
A = 1256
This is the area of a full circle, but we want half of that because we want the area of a semicircle instead. Since your teacher put 1256 for choice C in there, it seems like that is a trick answer.
We'll divide 1256 over 2 to get 1256/2 = 628 square meters as the final answer, which is choice D.
We can abbreviate "square meters" into "m^2".

Find the principal amount invested if the amount in a quarterly compounded account with a 3.07% interest rate is $5,993.79 after 66 months
Answers
Answer:
$5065.8332
Step-by-step explanation:
Given that :
Compound interest formula :
A = P(1 + r/n)^nt
t = period in years
n = number of compounding times per period, quarterly = 12/3 = 4
A = 5,993.79
r = 0.0307
t = 66 months = 66/12 = 5.5
5,993.79 = P(1 + 0.0307/4)^4*5.5
5,993.79 = P(1.007675)^22
5,993.79 = 1.1831795P
P = 5,993.79 / 1.1831795
P = 5065.8332
Hence, principal amount = $5065.8332

A support cable connects the top of a bridge tower to the road below.
The cable is 245.9 feet long and connects to the road at a point 200.7 feet away from the center of the bridge tower.
To the nearest tenth of a foot, how tall is the tower?
Answers
Answer:
the road is 142 ft away from the center of the bridge tower.
Step-by-step explanation:
Since, the bridge tower is standing vertical to the the road, therefore, the angle made by it is a right angle.
Therefore, the triangle made by cable(hypotenuse) and bridge tower (Perpendicular) on road (base) must be a right angled triangle.
Therefore, by Pythagoras theorem, we have
H² = P²+ B²
P²=H²-B²
P²=(245.9)²-(200.7)²
P=√20186.32=142.07

We call the square root curve a "relation" because it is not a function. A relation that is a function will have only one y-value for each x-value. For positive x-values, there are two square roots.
