Same-side interior angles where a transversal crosses parallel lines are supplementary:
The solutions to these equations can probably be done in your head:
- y = 180/(6+4) = 18
- x = (180-90)/5 = 18
The angles at the bottom of the figure, shown as different, are actually the same: 90°.
The angles at the top of the figure, shown as the same, are actually different: 108° on the left, 72° on the right.
Answer:
The sum will be positive because when using KCF ( keep change flip) the problem becomes 75-57 therefore the answer will be positive 18. hope this helps

Step-by-step explanation:
If the original pendulum completed one swing every 1.5 seconds. How long should the new pendulum be is: C. 55.9 centimeters.
<h3>How long should the new pendulum be</h3>
Using this formula
T=2π√I/g
Where:
T=1.5 seconds
l =length of pendulum
g= acceleration of gravity=9.8m/s²
Let plug in the formula
1.5 seconds=2π√I/9.8
l/9.8=0.05699
l=0.05699×9.8
l=0.5585
l=55.9 centimeters (Approximately)
Therefore How long should the new pendulum be is: C. 55.9 centimeters.

Answer:
If:
(1)
And we have to rewrite the following expresion in terms of 
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of 
, factorizing by the common factor:
Then, we can substitute by :
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is and the number that multiplies the variable (the coefficient) is 
, whereas the constant (which is the term with no variable) is
