A is the true answer and others are wrong
Answer:
A) x = 20
Step-by-step explanation:
ABCD is a rhombus, AC and BD are diagonals which intersect each other at point E.
Since, diagonals of a rhombus are perpendicular bisector.

Answer: 19.8 ft
Step-by-step explanation:
Use the Pythagorean Theorem formula to solve for how high the top of the ladder reach.
The formula says a^2 + b^2 = c^2
Where a and b are the two legs and C is the hypotenuse.
In this situation, the hypotenuse will be length of the ladder , and either a or b will be the length of the ladder from the building or the length of how long the ladder.
a will be 3 , and c will be 20. Input in the values into the formula and solve for b.
3^2 + b^2 = 20^2
9 + b^2 = 400
-9 -9
b^2 = 391
b =
b = 19.77371 round to the nearest tenth is , 19.8
Answer:
Step-by-step explanation:
![(\sqrt[4]{9})^{\frac{1}{2}x}=(9^{\frac{1}{4}})^{\frac{1}{2}x}\\\\=9^{\frac{1}{4}*\frac{1}{2}x}\\\\=9^{\frac{1}{8}x}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B9%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%3D%289%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%29%5E%7B%5Cfrac%7B1%7D%7B2%7Dx%7D%5C%5C%5C%5C%3D9%5E%7B%5Cfrac%7B1%7D%7B4%7D%2A%5Cfrac%7B1%7D%7B2%7Dx%7D%5C%5C%5C%5C%3D9%5E%7B%5Cfrac%7B1%7D%7B8%7Dx%7D)
