In angle xyz, the measure of angle z is 90 degrees, xz = 20, yx = 29, and zy = 21 what is the value of the cosine of angle x to the nearest hundredth

8121 because

130,000 divided by 16 is 8121

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
