Since perimeter is all of the sides added up..
And we have
side 1 = 4in
side 2 = 4in
side 3 = 5in
side 6 = 6in
Lets just add them all up
4 + 4 + 5 + 6 = 19
So the perimeter of the trapezoid is 19 inches

Answer:
y = 3
Step-by-step explanation:
39 = 13y
y = 3 (explanation: by dividing 13)
Check answer:
39 = 13(3)
39 = 39
Answer:
125
Step-by-step explanation:
120 - 90 = 25 x 5 = 125
X^2 + 2x + 8 = 0
(x + 1)^2 - 1 + 8 = 0
(x + 1)^2 = -7
x + 1 = sqrt (-7) = i sqrt7
x = -1 + i sqrt7
Its B
Answer:
12.87
Step-by-step explanation:
Since we know that line CD is a perpendicular bisector, triangle ACD is a right triangle, and thus we can apply the Pythagorean theorem to determine the length of side CD. Since the Pythagorean theorem states that a^2 + b^2 = c^2, where c is the hypotenuse and a and b are the adjacent sides, we can plug in the values of side AD and AC.
As side CD is the bisector of side AB, sides AD and DB are both half the length of side AB, so:
AD = 11/2
AD = 5.5
We now know two values of our equation, and thus we can solve for the missing third value.
5.5^2 + b^2 = 14^2
14^2 - 5.5^2 = b^2
196 - 30.25 = b^2
165.75 = b^2
b = 12.87
