Not sure what the length of the rectangle is but to find perimeter of a rectangle you can use the following formula
2w+2l= perimeter
The reason we multiply both the length and width by two is because there are two ends of the width and two ends of the length.
The other formula that would also work is as follows
w+w+l+l= perimeter
Hope it helps
Answer is 13a + 2b multiply everything in the parenthesis by 2 so 2 x b is 2b and 2 x 5a is 10a so 3a + 10a is 13a + 2b
Answer:
x=42
y=59
Step-by-step explanation:
Ok so first things first
the angle that is equal to 2x-11 is vertical to the angle that is equal to 73
meaning that these angles are congruent
so we setup an equation
2x-11=73 and solve for x
step 1 add 11 to each side
73+11=84
-11+11 cancels out
now we have
84=2x
step 2 divide each side by 2
84/2=42
so x=42
so we know that the angles that are listed bellow
(73, 48 and y)
are supplements meaning that they will add up to equal 180 so to find y we subtract the given angles
180-73-48=59 so y=59
