The figure below shows a triangle with vertices A and B on a circle and vertex C outside it. Side AC is tangent to the circle. S

JulsSmile [24]

Answer:

Step-by-step explanation:

First, one theorem states that (arc AB - arc AX) / 2 = angle ACB. We know that arc AB is 176, so we have

(176 - arc AX) /2 = ∠ACB

Next, the Inscribed Angle Theorem states that

arc AX/2 = ∠ABX

multiply both sides by 2

56 * 2 = arc AX = 112

Therefore, ∠ACB = (176-112)/2 = 64/2 = 32

Write the quadratic equation in factored form. Be sure to write the entire equation.

Ulleksa [173]

X^2-5x-24=0
I don't know you use which way, i just tell you the easy way i think.
x^2-5x-24=0
24=2x2x2x3
So we can have those two numbers: 3, -8
The answer is (x+3)(x-8)

it takes sami 10 minute to shovel the snow 20 m2 area. he charges 5 dollars for half an hour . how much will he charge to shovel

IgorLugansk [536]

First, we need to find the area of the sidewalk that he will be shoveling:
$A=l*w$

In this case, l=2m and w=40m. Then we have
$A=2*40=80m^{2}$

We know that he can shovel $20m^{2}$ in 10 minutes, so this would take him 40 minutes since 20*4=80. Now we just need to figure out how much this will cost. Since he charges $5.00 per half hour, we need to get 40 minutes in terms of half hours:
$\frac{40}{30}=\frac{4}{3}$

Last, we just multiply his half-hour rate by the amount of half hours he is shoveling for:
$\frac{4}{3}(5)=\frac{20}{3}$

I'll let you simplify the fraction.
