Answer:
Step-by-step explanation:
The tangent segment is perpendicular to the diameter, so the triangle is a right triangle (not just based on its appearance). A property of circles is: a tangent is perpendicular to the radius drawn to the point of tangency.
In the right triangle, one leg has length 12.6, and the hypotenuse has length 21.
Apply the Pythagorean Theorem: (leg)^2 + (leg)^2 = (hypotenuse)^2
Oh, and the diameter has length 2x!

For this case we have that by definition, the point-slope equation of a line is given by:

Where:
It is a point through which the line passes
m: It is the slope of the line
According to the data we have to:

Substituting:

Finally, the equation of the line is:

Answer:
sin=15/17
Step-by-step explanation:
Use the definition of sine to find the value of
sin (0)
sin (0) = opp/hyp
THEN
Substitute in the known values.
sin (0) = 15/17
According to my calculations the 30% of 570 is 171
10% of 570 is 57
times that by 3 and you get 171
