Answer:
76 degrees
180-38-38 is 104
180-104 is 76 since it's a straight line which equals to 180 degrees
40 to the second power is 1600!
Find the length of the radius.

Find the length of the diameter.
d = 2r = 2 × 5√2 = 10√2
Point B must lie on a line AC, where C is a center of a circle.
Find equation of line AC.
A(–4, 6), C(3, 5)
The distance from B(x, y) to C(3, 5) is 5√2.

Solve system of equations.


Point B could have coordinates

But (–4, 6) are the coordinates of point A.
Therefore, point B has coordinates (10,4).

Answer:
The solution set is {4, -1}
Step-by-step explanation:
6x²- 18x -18 = 6
6x²- 18x -18 - 6 = 0
6x²- 18x -24 = 0
6(x² - 3x - 4) = 0
6(x - 4)(x + 1) = 0
6 = 0 not true
x - 4 = 0 ; x + 1 = 0
x = 4 x = - 1
The solution set is {4, -1}
