Answer:

15

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(5+x) * 5 = 10^2

Distribute

25 +5x = 100

Subtract 25 from each side

25-25 +5x = 100-25

5x= 75

Divide by 5

5x/5 = 75/5

x = 15

Which graph best represents the equation 2x + 4y equals negative 8
Hitman42 [59]
You have to solve for y
Subtract 2x to the other side
Divide both sides by 4
y=-1x/2-2
Graph D has a slope of -1/2 and a y-intercept of -2

ΔABC is a right triangle in which is a right angle, AB = 1, AC = 2, and BC = .
ollegr [7]
We are asked to solve for the measurement of side BC in the given right triangle ΔABC and other side measurements were also given such as AB=1 and AC = 2. Since this is a right triangle, we can use and apply the Pythagorean theorem c²= a² + b² and the solution is shown below:
c = AC
b = BC
a = AB
AC² = AB² + BC² , substitute values we have:
2² = 1² + BC²
BC² = 4-1
BC = √3
BC = 1.732

The answer for the length of BC is 1.732 units.
