Answer:
3
Step-by-step explanation:
Vertical angles share a vertex point, and have opposite rays for sides. In short, they are across the point of intersection from each other. Vertical angles do not have a common side (they are <em>not</em> adjacent).
The first part of the problem is to identify angle NCA. That is shown in red in the attachment. The vertical angle is across the point of intersection. It is angle 3.
Given:
V = 5x² + 15x + 2, the volume
h = 5x, the height
Let A = the area of the base.
Because V = Ah, therefore
A*(5x) = 5x² + 15x + 2
Answer:
Small problem....
There is no graph!
ill be happy to solve this if i saw a graph
Step-by-step explanation:
if two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
in terms of this example :
AP × BP = CP × PD
(5+7) × 7 = (14 + PD) × PD
12×7 = 14×PD + PD²
84 = 14×PD + PD²
PD² + 14×PD - 84 = 0
this quadratic equation can be solved by this generic formula :
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = PD
a = 1
b = 14
c = -84
PD = (-14 ± sqrt(196 - 4×1×-84))/(2×1) =
= (-14 ± sqrt(196 + 336))/2 = (-14 ± sqrt(532))/2 =
= (-14 ± sqrt(4×133))/2 = (-14 ± 2×sqrt(133))/2 =
= -7 ± sqrt(133)
PD1 = -7 + sqrt(133) = 4.532562595...
PD2 = -7 - sqrt(133) that is negative and does not make sense for a distance.
I don't know the format you need to have the answer in,
but it is in value
4.532562595... or -7 + sqrt(133)
The answer is 12*x and x=18 because you dont know what x is so you replace it with x. Then when done writing the equation you start substituting the 18 to x which would give you 12*18 then multiply.
