A² = b² + c² - 2bcCos A
a² = 11² + 13² - 2(11)(13)Cos(108)
a² = 378.38
a = √378.38
a = 19.45
Answer: 19.45
Answer:

Step-by-step explanation:
An isosceles ∆ has 2 equal sides. The perimeter of a ∆ is the sum of all its sides.
Given that the perimeter of the triangle above is "at least 137 ft", this means the sum of all its sides is equal to or greater than 137 ft.
Thus, using inequality, this can be represented as:

Solve for x

Add like terms

Subtract 17 from both sides


Divide both sides by 8


It would just be 80. They are both in the bottom right and I'm guessing this is one the problems that look like this:
-------/------
-----/--------
So just think about it. If the line is a straight line through two parallel lines then the angles of the two intersections should be the same. Basically because they are both on the bottom right they will be the same. Glad to help!
