What is tangent to a circle?A line segment which touches a circle specified to only one point is called a tangent to that circle.
1. given
2. A line is a tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency.
3. Since the tangent is perpendicular to radius i.e., EFC is right angle then,
angle EFC =90
4. Sum of interior angles of a triangle is 180°.
5. proved above: angle EFC= 90
6. FEC + ECF= 180-90=90
7. As proved above
FEC + ECF=90, its shows that angle FEC and ECF are complementary angle.

B is the midpoint of AC, what in the measure of AB if AC 82cm?
Answer:
AB = 41 cm
Step-by-step explanation:
If B is the midpoint of AC, then B splits AC into 2 equal halves: AB & BC.
Therefore, AB = ½ of AC.
Given, AC = 82 cm.
So,
AB = ½ × AC
AB = 82/2
AB = 41 cm

A gym has an enrollment fee of $80. There is also a $25 fee per month of membership.
This is like a linear equation, (y = mx + b) where the cost per month is 25, and our b is the 80 to join in the first place:
y = 20x + 80
You did not share how much was paid for the membership, but if you put the total cost into y, then you can solve for x. Or you can find the total cost by entering in the number of months for x.
Answer:
Equation given
80+25(y)=x
y= Per month(So the amount of months that passed)

Consider the equation 5 – 3(2x – 7) = 12 – 5(x – 2). Is x = 2 a solution to this
equation? Is x = 4 a solution to this equation?
Answer:
[tex]\sf x=4[/tex]
Step-by-step explanation:
[tex]\sf 5 - 3(2x - 7)=12 - 5(x - 2)[/tex]
To get rid of the parentheses, we'll apply the distributive property. Staring with the left side, multiply -3 by (2x-7).
[tex]\sf 5 - 6x+21=12 - 5(x - 2)[/tex]
5+ 21= 26
[tex]\sf 26 - 6x=12 - 5(x - 2)[/tex]
Now, let's do the same thing to the right side. Multiply -5 by (x-2) »12−5x+10, than add 12+ 10 = 22 .
[tex]\sf 26 - 6x=22 - 5x[/tex]
Combine like terms.
[tex]\sf 26 - x=22[/tex]
Subtract 26 from both sides.
[tex] \sf - x= - 4[/tex]
Multiply both sides by -1.
[tex]\sf x=4[/tex]

which equation represents a line that passed through (2,-1:2) and has a sloe of 3
The equation that represents a line that passed through (2,-1:2) and has a slope of 3 is y = 3x - 18
How to determine the equation of the line?The points are given as:
(x1, y1) = (2, -12)
The slope is given as:
m = 3
The equation of the line is calculated using:
y = m(x - x1) + y1
So, we have:
y = 3(x - 2) - 12
Open the bracket
y = 3x - 6 - 12
Evaluate
y = 3x - 18
Hence, the equation of the line is y = 3x - 18

What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangle ΔABC and triangle ΔGFC are similar triangles. Then we have
GF / BA = CF / BC
GF / 5.62 = 8.88 / 12.42
GF = 4.018
GF ≅ 4.02
The triangle ΔABC and triangle ΔIHC are similar triangles. Then we have
IH / BA = HC / BC
IH / 5.62 = 5.02 / 12.42
IH = 2.271
IH ≅ 2.27
Then the angle ∠ACB will be
∠ACB = tan⁻¹ (5.62 / 12.42)
∠ACB = tan⁻¹ 0.452
∠ACB = 24.35°

Step-by-step explanation:
the first number of a exponential function is the y intercept when x = 0,
so we now the number will be 5 leaving only answers c or d
the easiest way see which one is correct is by inputting the numbers for x to find y so...
c) 5 x 2^1 = 5 x 2 = 10 so x = 1 than y = 10
d) 5 x 1/2^1 = 5 x 1/2 = 2.5 so x = 1 than y = 2.5
the table states that y = 10 when x = 1 making c correct
