XY is a diameter of a circle and Z is a point on the circle such that ZY=6. If the area of the triangle XYZ is 18 square root 3 find the length of arc XZ
4π
Step-by-step explanation:As shown in the diagram, triangle XYZ is a right triangle. Therefore, its area (A) is given by:
A = [tex]\frac{1}{2}[/tex] x b x h -------------(i)
Where;
A = 18[tex]\sqrt{3}[/tex]
b = XZ = base of the triangle
h = YZ = height of the triangle = 6
Substitute these values into equation(i) and solve as follows:
18[tex]\sqrt{3}[/tex] = [tex]\frac{1}{2}[/tex] x b x 6
18[tex]\sqrt{3}[/tex] = 3b
Divide through by 3
6[tex]\sqrt{3}[/tex] = b
Therefore, b = XZ = 6[tex]\sqrt{3}[/tex]
Now, assume that the circle is centered at O;
Triangle XOZ is isosceles, therefore the following are true;
(i) |OZ| = |OX|
(ii) XZO = ZXO = 30°
(iii) XOZ + XZO + ZXO = 180° [sum of angles in a triangle]
=> XOZ + 30° + 30° = 180°
=> XOZ + 60° = 180°
=> XOZ = 180° - 60°
=> XOZ = 120°
Therefore we can calculate the radius |OZ| of the circle using sine rule as follows;
[tex]\frac{sin|XOZ|}{XZ} = \frac{sin|ZXO|}{OZ}[/tex]
[tex]\frac{sin120}{6\sqrt{3} } = \frac{sin 30}{OZ}[/tex]
[tex]\frac{\sqrt{3} /2}{6\sqrt{3} } = \frac{1/2}{|OZ|}[/tex]
[tex]\frac{1}{12} = \frac{1}{2|OZ|}[/tex]
[tex]\frac{1}{6} = \frac{1}{|OZ|}[/tex]
|OZ| = 6
The radius of the circle is therefore 6.
Now, let's calculate the length of the arc XZ
The length(L) of an arc is given by;
L = θ / 360 x 2 π r ------------------(ii)
Where;
θ = angle subtended by the arc at the center.
r = radius of the circle.
In our case,
θ = ZOX = 120°
r = |OZ| = 6
Substitute these values into equation (ii) as follows;
L = 120/360 x 2π x 6
L = 4π
Therefore the length of the arc XZ is 4π

Step-by-step explanation:
Basically you can see that one side of the "triangle" is 3, and the other is 9 (based on the distance, assuming that the line would be a hypotenuse). From here all you have to do is square 3 and square 9, add them, and find the square root
√(9+81) = 10

One leg of triangle is 7 inches longer than the other leg. The hypotenuse is 8 inches longer than the shorter leg. The perimeter of the triangle is
Answer:
5 ; 12 ; 13
Step-by-step explanation:
Let :
Shorter leg = x
Other leg = x + 7
Hypotenus = x + 8
Recall:
Hypotenus² = opposite² + adjacent²
(x+8)² = x² + (x+7)²
x² + 16x + 64 = x² + x² + 14x + 49
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x(x - 5) +3(x - 5) = 0
(x + 3) = 0 ; x = - 3
(x - 5) = 0 ; x = 5
Side can't be negative ;
Hence,
x = shorter side = 5
Other side = x + 7 = 5 + 7 = 12
Hypotenus = x + 8 = 5 + 8 = 13
Mario's pizzeria puts olive pieces along the outer edge (periphery) of the crust of its 18-inch (diameter) pizza. Assuming that the pizza is cut into eight slices and that there is at least one olive piece per inch of crust, find how many olive pieces you will get in one slice of pizza.
Answer:
Radius= 9 in.
Circumference= 2π*9=56 (rounded)
So you'd get at least 56 pieces in the crust of the pizza.
Divide the answer by 8 to get the average number of piece per slice.
56/8
= 7 pieces approximately.

Answer:
The area of the shape shown is [tex]12.5units^2[/tex]
Step-by-step explanation:
So the formula for solving the area of trapezoids is:
(top base + bottom base) x height ÷ 2
In this case, the equation is:
(7.5 + 2.5) x 2.5 ÷ 2
Let's solve it!
(7.5 + 2.5) x 2.5 ÷ 2 =
10 x 2.5 ÷ 2 =
25 ÷ 2 =
12.5
Which will get 12.5 as an answer.
Since the unit isn't listed, we will just write [tex]unit^2[/tex] instead of [tex]cm^2[/tex] or [tex]in^2[/tex]
Answer:
12.5
Step-by-step explanation:
I split the shape into two shapes: one square, and two identical right triangles
The area of the square is a^2 so 2.5^2 so 6.25
The area of the right triangle A=ab/2 we know one side 2.5 and the other side is just 7.5-2.5 and then halved so also 2.5.
The area of this triangle is 3.125*2 because there are 2 then +6.25
=12.5
Edit: Just realized there was a much simpler way to do this lol I just normally can't do math the regular way. You can just do the area of the trapezoid
my smart people help me love yall! ^^

HURRY WILL GIVE BRAINLIEST Maria lives at the corner of 3rd Avenue and 5th Street. Pierre lives at the corner of 9th Avenue and 14th Street. They decide to leave their houses and meet at the library located 13of the distance from Maria's apartment. In their city, avenues run eastto west and streets run north to south. If each street and avenue is spaced 1 unit apart, at what intersection will Pierre and Maria meet?
Answer:
5th Avenue and 8th street
Step-by-step explanation:
The points are (3,5) and (9,14) for their locations where x= avenue and y= street.
The distance is 1/3 so it can be calculated in the following way
1/3 of ( 9-3) +3 = 1/3*6 + 3= 2+3= 5
1/3 of (14-5) + 5= 1/3*9 + 5= 3+5=8
5th Avenue and 8th street
Pierre and Maria will meet at 5th Avenue and 8th street

Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i

What is question A and B?
Answer:
Jo turned around and walked back to the starting point
8 km/hr
Step-by-step explanation:
4 km/one-half hr = 8 km/hr
Step-by-step explanation:
A)
If we look at the graph at 10 mins its evident that there has been some movement meaning Joes has moved 1km (as we can see in the graph) away from the starting point.
B)
For the last 30 mins of the graph we can see some changes.
so Joe started at 30 mins and ended at 60mins so there is a difference of 30 mins. In those 30 mins Joe moved from 0km to 4km. Meaning that Joe moved at 4km in 30 mins.
We are going to work this out in KPH. Since we have 30 mins and the unit we are using to measure his speed is measured in hours, we need to double it along with the kilometres he moved so it stays fair and constant. so we will have 8km and 60 min (1 hour). Therefore Joe moved at 8kph.
Hope this helps

Answer:
C) {6+√43, 6-√43}
Step-by-step explanation:
Applying,
x = [-b±√(b²-4ac)]/2a.................... Equation 1
From the question,
Given: a = 1, b = -12, c = 7
Substitute these values into equation 1
x = [-(-12)±√(-12²+4×1×7)]/2×1
x = [12±√(144+28)]/2
x = [12±√172]/2
either,
x = (12-√172)/2
x = (12-2√43)2
x = (6+√43)
or
x = (12+√172)/2
x = (12+2√43)/2
x = (6+√43)
Hence,
The right answer is C). {6+√43, 6-√43}

Find the function of the first two points
slope = delta y/delta x
slope = y1-y2/x1-x2
slope = (11-(-1))/(-10-1)
slope = 12/-11
Find the y intercept
y=(-12/11)x+b
-1 = (-12/11)*-1+b
-1 = 12/11+b
-23/11=b
y=(-12/11)x-23/11
Plug in x to find y
y=(-12/11)2-23/11

Answer: type this in bitly
Step-by-step explanation: 3f3FcEi
The value of x is 5 if pq=3x+4 and the perimeter of pqr=57 after using the concept of the triangle.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that:
if PQ = 3x+4 and the perimeter of PQR = 57,
3(3x + 4) = 57
9x + 12 = 57
9x = 45
x = 5
Thus, the value of x is 5 if pq=3x+4 and the perimeter of pqr=57 after using the concept of the triangle.
