Answer:
45
Step-by-step explanation:
KL- because triangle is a isosceles
(base angles are congruent)
Answer:
Step-by-step explanation:
Midsegment is the half the length of the parallel side of the triangle.
So parallel sides of the triangles, which are the side of the base of the pyramid are:
Answer:
E) 1/2
Step-by-step explanation:
This is no ordinary problem. It actually requires you to solve two different problems in order to figure out the correct answer.
First, we must figure out what the hypotenuse of the triangle is. We have the two small sides (5 and 12), but don't have the larger side. To find this, we must use the Pythagorean theorem: 
Let's plug in our a and b values

Simplify


Square both sides

But sadly, we aren't done yet. Now we know the length of the whole hypotenuse side. Time to figure out what X is by a simple equation.

Simplify

Divide by 26
Answer is 1/2
