Question fifty. On a chart from a good go camping. You will want to create a circular taking walks roadway one to links new pool at the (10, 20), the kind cardio at the (sixteen, 2). in addition to tennis-court on (dos, 4).

After that solve the issue

Answer: The middle of brand new circular street interracial dating central beğenenleri görme has reached (ten, 10) and distance of game street try 10 systems.

Let the centre of the circle be at O (x, y) Slope of AB = \(\frac < 20> < 10>\) = 2 The slope of XO must be \(\frac < -1> < 2>\) the negative reciprocal of the slope of AB as the 2 lines are perpendicular Slope of XO = \(\frac < y> < x>\) = \(\frac < -1> < 2>\) y – 12 = -0.5x + 3 0.5x + y = 12 + 3 = 15 x + 2y = 30 The slope of BC = \(\frac < 2> < 16>\) = -3 The slope of XO must be \(\frac < 1> < 3>\) = \(\frac < 11> < 13>\) 33 – 3y = 13 – x x – 3y = -33 + 13 = -20 Subtrcat two equations x + 2y – x + 3y = 30 + 20 y = 10 x – 30 = -20 x = 10 r = v(10 – 2)? + (10 – 4)? r = 10

Question 51. Critical Convinced Area D ‘s the incenter away from ?ABC. Establish a term into the size x in terms of the about three side lengths Ab, Ac, and BC.

Select the coordinates of your heart of your network additionally the radius of one’s circle

The endpoints of \(\overline\) are given. Find the coordinates of the midpoint M. Then find AB. Question 52. A(- 3, 5), B(3, 5)
