1) The supplement of 72° is 180°-72° = 108° . (bottom // with right secant)
2) (3z + 18)° = 108° ( in a para llelogram opposite angles are equal)
Then 3z+18 = 108 and 3z° = 90° → z = 30°
3) (3y)° = 108° (vertical angles) , 3y° = 108 and y = 36°
4) 3y = x° (corresponding angles) but 3y = 108, then x = 108°
(Mind you I am calculating the ∠ x, y, and z. To find the angles of the parallelogram replace x,y and z by their respective values
The answer is approximately A ~ 688.19
Which of the following is the simplified form of [1] fifth root of x times the [2] fifth root of x times [3] the fifth root of x times [4] the fifth root of x?
That's
![( \sqrt[5] x)^4 = x^{\frac 4 5}](https://tex.z-dn.net/?f=%20%28%20%5Csqrt%5B5%5D%20x%29%5E4%20%3D%20x%5E%7B%5Cfrac%204%205%7D)
That looks like the second choice.
