In the diagram, g ∥ h, m∠1 = (4x + 36)°, and
m∠2 = (3x – 3)°.

Lines g and h are parallel and diagonal down to the right. A horizontal line cuts through lines g and h. Another vertical line goes through lines g and h and the horizontal line. At the intersection of the vertical line with line h, the bottom left angle is angle 1 and the bottom right angle is angle 3. At the intersection of the vertical line with line g, the uppercase left angle is angle 2.

What is the measure of ∠3?

21°
60°
120°
159

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)

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
