X = 116 degrees
The sum of the three angles in a triangle add up to 180 degrees
Add up the two known angles
32 + 32 = 64
Subtract that from the total measure
180-64 = 116
Since 116 and x are vertical angles, they are congruent, making x equal to 116

What is the difference between (-58) and (+35) ?

romanna [79]

To do this question, you are best splitting it into two halves: getting to 0, and then 35
Starting at -58, we want to get to 0
-58 + 58 = 0
Then, we get to 35 from 0
0 + 35 = 35
Now, add the two values together
58 + 35 = 93
The difference is 93

Simplify the expression so there is only one positive power for each base. (5^-2 x 4^-4)^-2

$(a\cdot b)^n=a^n\cdot b^n\\(a^n)^m=a^{n\cdot m}\\\\(5^{-2}\cdot4^{-4})^{-2}=(5^{-2})^{-2}\cdot(4^{-4})^{-2}=5^{-2\cdot(-2)}\cdot4^{-4\cdot(-2)}\\\\=\boxed{5^4\cdot4^8}\to\fbox{A.}$
