13 pi over 6 is equivalent to 390 degrees. This is a first quadrant degree angle. The reference angle is the supplementary angle of the angle given. The reference angle is equal to the didifferencef 3 pi and 13 pi over 6. This is equal to 5 pi over 6.
The rule is: Before you can add or subtract fractions, they must have
the same denominator.
For this little problem, don't worry about the signs yet. Just make both
fractions have the same denominator. I suggest you change the first one
to something over 250.
When your fractions have the same denominator, you get the sum or difference
like this:
-- The numerator of the answer is the sum or difference of the two numerators.
-- The denominator of the answer is the same as the denominator of the two fractions.
Second 3:22. Because 33/11 is 3 and 11x2 is 22
The length of a rectangle is 2 centimeters longer than its width. The perimeter is 16 centimeters.
Length of rectangle = L
Width of the rectangle = W
The length of a rectangle is 2 centimeters longer than its width.
So L = W + 2
Perimeter of rectangle = 2* length + 2* width
Given perimeter = 16cm
Subtract 4 on both sides
12 = 4W
Divide by 4 on both sides
3 = W
So width of the rectangle = 3 cm
Length = W + 2 = 3+2 = 5 cm
