Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40

Answer:
A. the difference of two squares
Step-by-step explanation:
Please use the symbol " ^ " to indicate exponentiation.
Then we have x^2 - 11^2, which is the difference of two squares:
x^2 is a square, the square of x; and 11^2 is a square, the square of 11.
A. the difference of two squares
Note that a "difference of squares" is easily factored:
a² - b² = (a - b)(a + b)
and so your x² - 11² factors as follows: (x - 11)(x + 11)
