Circle V is shown. Line segments Y V and W V are radii. Tangents Y X and W X intersect at point X outside of the circle. The length of V Y is 5. Angle V is a right angle. What is the measure of circumscribed ∠X? A 45 B 50 C 90 D95

The correct option is;

C 90°

Step-by-step explanation:

Here we have;

Angle V = 90°

Whereby, YX and WX are tangents, and YV and WV are radii then ;

Angle Y = 90° and

Angle  W = 90°

Therefore we have sum of angles V, Y, W and X given by the following relation;

V + Y + W + X = 360° (Sum of interior angles of a polygon angle)

Therefore;

90° + 90° + 90° + X = 360°

270° + X = 360

X = 360° - 270° = 90°

Hence the correct option is X = 90°.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
