If m∠o = 111, find the value of x in this figure. - 55.5 - 69 - 291 - 222

Option 2. 69° is the right answer.

Step-by-step explanation:

In this question there are two tangents MN and MP drawn on a circle O and ∠PON = 111° and ∠PMN=x°

We have to find the vale of x.

As we know Radius of a circle is always perpendicular to the tangent drawn so ∠ ONM = ∠OPM = 90°

And sum of all angles of OPMN = 4×90°=360°

⇒∠ONM+∠NMP+∠MPO+∠PON = 360°

⇒ 90°+X°+90°+111°=360°

⇒ 291°+X°=360°

⇒ X° = 360°-291° = 69°

⇒ X° = 69°

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)
