Radius of inscribed circle of triangle HJK is 6 unit

Step-by-step explanation:

As shown in figure,

The triangle HJK has In-circle or inscribed circle of radius PL(or PM or PN)

Since, PL and PM is radius of same in-circle,

PL = PM

Given that PL=3x+4 and PM =6x-14

3x+4=6x-14

3x=18

x=6

Thus, The correct answer is B). 6

What is the equation of a circle that has a center at (-4, 10) and a radius of 8?

mars1129 [50]

Answer:

The equation of the circle is $(x + 4)^2 + (y - 10)^2 = 64$ , third option is correct.

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

Center at (-4, 10)

This means that $x_0 = -4, y_0 = 10$ .

Radius of 8:

This means that $r = 8$ . So

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - (-4))^2 + (y - 10)^2 = 8^2$

$(x + 4)^2 + (y - 10)^2 = 64$

The equation of the circle is $(x + 4)^2 + (y - 10)^2 = 64$ , third option is correct.
