In the figure below, AD = 5 and BC = 4.5. Compare m∠ABD and m∠BDC.

a)m∠ABD < m∠BDC

b)m∠ABD > m∠BDC

c)m∠ABD = m∠BDC

The answer is C.

One word for ya friend ☺

Congruence!

When you cut a rectangle in half at a point of symmetry you get two sides with equal measurements. So the angles are in fact equivalent to one another :))

I hope this helps! If you need any more help, feel free to hmu!!

In a triangle if side length opposite to angle is greater than this angle must be greater,

Triangle ABD and CBD are similar and

AD=5 greater than BC=4.5

Angle opposite to AD is greater which is angle ABD,

so the angle ABD is greater then the Angle BDC

That implies option B is correct.  

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)
