First, multiply both sides by 1000.
1000*c = w*t*c
Since c is on both sides, they cancel each other out
1000 = w*t
Divide both sides by w.
1000/w = t
The value of x is 15.56.
Solution:
Tangent and Secant theorem:
If one secant and one tangent are drawn to a circle from one exterior point, then the square of the length of the tangent is equal to the product of the external secant segment and the total length of the secant.
BE = 22 BD = x, CD = x
BC = x + x = 2x
By the tangent and secant theorem,



Divide by 2 on both sides of the equation, we get

Take square root on both side of the equation.
x = 15.56
Hence the value of x is 15.56.
Answer:
<5 = 132°
<7 = 132°
<8 = 48°
Step-by-step explanation:
aAgle 2 and angle 5 are supplementary which means their sum is 180° so angle 5 is 180 - 48 = 32°
Angle 5 and angle 7 are congruent so their measures are equal 132°
Angle 8 and angle 2 are congruent and equal to each other as well
