For this case we have an equation with a variable of the form
. Where
. Given the value of
, we want to find the value of the variable "x". So, we have:

We must clear "x", for this, we add "19" to both sides of the equation:

We divide between "3" on both sides of the equation:

Thus, the value of the variable "x" is 30.
Answer:

Option A
Answer:
1 7/12
Step-by-step explanation:
here you go :)
Larger triangle’s base length
a^2 + b^2 = c^2
a^2 + 3^2 = 8^2
a^2 = 8^2 - (3^2)
sqrt(a^2) = sqrt(55)
a = sqrt(55)
__________________
Smaller triangle’s base length:
The same formula applies.
a^2 + 3^2 = 5^2
a^2 = 5^2 - (3^2)
sqrt(a^2) = sqrt(16)
a = 4
____________
The finale!
Add the two side lengths of a, which is sqrt(55) + 4 (exact answer)
or... 11.416 (unrounded to thousandths place)
Good luck to you!
Answer: I believe it is "It also has a reflectional symmetry
Step-by-step explanation: Because even if you rotate the picture if you fold it in half it will fit perfectly with each other
