Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9
Answer:
66 feet
Step-by-step explanation:
Parallelograms have 2 pair of parallel sides that are congruent to each other.
In parallelogram ABCD, we can say:
AB = DC
and
BC = AD
AB and DC are given, and they are equal. So we can say:
AB = DC
6x - 2 = 3x + 13
Now we can solve for x:
6x - 2 = 3x + 13
6x - 3x = 13 + 2
3x = 15
x = 15/3
x = 5
So,
AB = 6x - 2
AB = 6(5) - 2 = 28
So, DC = 28
We are also given AD = 5, so BC = 5 as well [since AD = BC]
Now, we know the length of all 4 sides.
The perimeter is the sum of all 4 sides. Hence,
Perimeter = 28 + 28 + 5 + 5 = 66 feet
