Answer:
Centre = (2, -3)
radius = 5units
Step-by-step explanation:
The standard form of a circle is expressed as;
x²+y²+2gx+2fy+c = 0
Centre = (-g, -f)
radius r = √g²+f²-c
Given the equation;
x²+y²-4x+6y-12 = 0
Compare
2gx = -4x
2g = -4
g = -2
Similarly;
2fy = 6y
2f = 6
f = 3
Centre = (-(-2), -3)
Centre = (2, -3)
Radius = r = √(-2)²+3²+12
r = √4+9+12
r = √25
r = 5 units

The value of x in the triangle is 12/7.
We have,
Using the Midsegment theorem.
The midsegment is half the base of the triangle.
Now,
2x - 7 = 1/2 x 10
2 (2x - 7) = 10
14x - 14 = 10
Add 14 on both sides.
14x = 10 + 14
14x = 24
Divide 14 on both sides.
x = 24/14
x = 12/7
Thus,
The value of x in the triangle is 12/7.

HELP!!! Find the measure of each angle.
Answer:
Step-by-step explanation:
This figure is called a cyclic quadrilateral. The vertices of all sides lie on a circle.
That's property one.
Property 2 is that the opposite angles add to 180 degrees.
6y - 4 + 5y - 3 = 180 is the y angles. Combine like terms.
11y - 7 = 180 Add 7 to both sides.
11y - 7 + 7 = 180 + 7
11y = 187 Divide by 11
y = 187/11
y = 17
H = 17 * 6 - 4
H = 102 - 4
H = 98
F = 5y - 3
F = 5*17 - 3
F = 85 - 3
F = 82
=====================
11x + 8 + 8x + 1 = 180
19x + 9 = 180
19x = 171
x = 171/19
x = 9
E = 9*11 + 8
E = 99+8
E = 107
G = 8*9 + 1
G = 72 + 1
G = 73
The central angle of arc ST is 70 degrees. What is the measure of an inscribed
angle whose endpoints are points S and T?
Answer:
35
Step-by-step explanation:
The measure of an inscribed angle whose endpoints are points S and T will be 35°.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
The central angle of arc ST is 70°.
The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have
Inscribed angle = 70° / 2
Inscribed angle = 35°
The measure of an inscribed angle whose endpoints are points S and T will be 35°.

Zane and his favorite geometry student, , have just set sail for a day of fun on lake Erie. A spring squall quickly forms and catches you off guard, leaving you adrift on the lake. Zane suddenly discovers he has an irrational fear of water and is reduced to hugging the mast. You hear Sherman barking from the top of a lighthouse to help guide you to shore. In order to save Zane and yourself, you must calculate how far away you are from this lighthouse. Using a range finder, you expertly measure the distance from the sailboat to the top of the lighthouse at 350 yards.
angle B is 40 degrees.
(a) Based on the above information, find the distance across the water from the sailboat to the island
where the lighthouse is standing. You can only use trigonometry to solve. You must show all work for
credit. Round your answer to the nearest whole number if needed.
(b)Calculate the height of the lighthouse. You can only use trigonometry or Pythagorean Theorem to
solve.
Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.
_________________________________________________________
According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).
Θ = 40hyoptenuse = 350adjacent = xcosine40 = x/350
[multiply both sides by 350]
350 · cosine40 = x
[put calculator in degree mode]
x ≈ 268 yards
So, the distance across the water from sailboat to the island is 268 yards.
_________________________________________________________
Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).
a^2 + b^2 = c^2
a = ? (opposite or height)b = 268 (adjacent)c = 350 (hypotenuse)a^2 + (268)^2 = (350)^2
a^2 + 71824 = 122500
a^2 = 122500 - 71824
a^2 = 50676
[square both sides]
[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]
a = [tex]\sqrt{50676}[/tex]
a ≈ 225
So, the height, opposite, of the lighthouse is 225 yards.

What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called the average of the values of the considered data set.
It serves as the predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.
