Answer:
the pythagorean theorem is an equation to figure out the side of a triangle. theformula is a squared plus b squared equals c squared.
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
The exterior angle of the triangle is equal to the sum of the opposite interior angles
11x+2 = 6x+2 + 40
Combine like terms
11x+2 = 6x+42
Subtract 6x from each side
11x+2-6x = 6x+42-6x
5x+2 = 42
Subtract 2 from each side
5x+2-2 = 42-2
5x = 40
Divide each side by 5
5x/5 = 40/5
x = 8
A variable is a letter, for example x, y or z, that represents an unspecified number.
6 + x = 12
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12.
