AC = 13 in the image shown. Is BC tangent to circle A?
Ganezh [65]

Answer:

Yes, because 52 + 122 = 132.

Step-by-step explanation:

A line through a point on a circle is tangent at the point if it is perpendicular to the radius drawn to the point of tangency. The Pythagorean Theorem only works for right triangles.

Solve the system by substitution. Check your solution. A minus 1.2 b = negative 3. 0.2 b + 0.6 a = 12 a. (15, 15) c. (13, 12) b.
Mrrafil [7]

Answer:

The answer to the question is -1.32

Step-by-step explanation:

The first step will be to write out the equation that we are working with:

This equation is

0.2b + 0.6a = 12

The next step is to write out the values of the figures that we are substituting:

a = -1.2 b=-3

Substitution in mathematics can best be understood as "something being used in place of another thing". This means that wherever the first variable appears in an equation, the substituting values will replace it and multiply the number it is attached to.

In this case, we will replace the 'b' and the 'a' with the - 1.2 and - 3 respectively.

0.2(-3) + 0.6(-1.2) = -1.32
