AB and AC are tangent. Find AB
LuckyWell [14K]

Answer:

AB =  \frac{11}{2}

Step-by-step explanation:

Given

The above diagram

AB = 3y + 4

AC = 11y

Required

Determine length AB

Tangents drawn from the same point of a circle are equal;

<em>This implies that</em>

AB = AC

Substitute values for AB and AC

3y + 4 =11y

Subtract 3y from both sides

3y - 3y + 4 = 11y - 3y

4 = 8y

Divide both sides by 8

\frac{4}{8} = \frac{8y}{8}

\frac{4}{8} = y

\frac{1}{2} = y

Substitute \frac{1}{2} for y in AB = 3y + 4

AB = 3 * \frac{1}{2} + 4

AB =  \frac{3}{2} + 4

AB =  \frac{3 + 8}{2}

AB =  \frac{11}{2}

Graph a right triangle with the two points 4,5 and -4,8​
Katyanochek1 [597]

Answer:

Step-by-step explanation:

Please write points using parentheses:  (4, 5) and (-4, 8}.

​

(4, 5) is in the 1st quadrant and (-4, 8} is in the 2nd. Reversing the order of these two points yields (-4, 8) and (4, 5).  From this we can see that while moving from (-4, 8) to (4, 5) involves following a line with negative slope (because the y-coordinate decreases from 8 to 5 as the x-coordinate increases from -4 to +4).  This sloping line is the hypotenuse of a right triangle.  Draw a vertical line segment through (-4, 8) and a horizontal line segment through (4, 5).  This hypotenuse, the vertical line segment and the horizontal line segment are the boundaries of the desired right triangle.
