AB and BC are tangents to P. what is the value of x? this is really so confusing

Westkost [7]

1. Angle PAB is 90 degrees, as it is formed from the tanget to the circle at A, and the radius drawn to A.

2. AB=BC, because tangents drawn to a circle from the same point are equal.

3. PB is Common, so by the side-side-side congruence postulate, triangles ABP and CBP are congruent.

4. So measure of m(BPA)=x/2 and m(ABP)=73/2.

5. $\frac{x}{2}+90+ \frac{73}{2}=180$

$\frac{x+73}{2}=90$

$x+73=180$ , x= 107 degrees.

Which expression is equivalent to the area of square A, in square inches?

Setler [38]

Answer:

length of 1 side of A, using the Pyth. Thm. and the dimensions of the other two squares: (side of A)^2 = (10 in)^2 + (24 in)^2. Then:

(side of A)^2 = 100+ 576 in^2 = 676 in^2.

Here I have not bothered to solve for the length of the side of A, since we want the area of square A. But if you do want the side length, find it: sqrt(676) = 26 in. Then the area of A is (26 in)^2 = 676 in^2.

Then the area of square A is (26 in)^2 =

Please help. What is the circumference of the circle? <br><br> (X+4)^2+(y-5)^2=81

PIT_PIT [208]

the radius: r^2 = 81

r =9

c = 2*pi*r

= 2 * pi * 9

= 18 *pi
