the picture in the attached figure
we know that
if ABC is an isosceles triangle
then
AB=BC
angle A=angle C=45 degrees
and
triangle ABD and triangle BDC also are isosceles triangles
AD=BD=x
DC=BD=x
the hypotenuse AC is equal to
To find the length AB applying the Pythagorean Theorem
remember that AB=BC
therefore
the answer is
the length of one leg of the large right triangle in terms of x is equal to 
Here you go, hope this helps!

Answer:
3/20
Step-by-step explanation:
Total number of students = 15 + 10 = 25
Number of girls = 10
Number of ways to select 2 students =
Number of ways to select 2 girls =
Compute the probability of selecting two girls as follows:
Thus, the probability that both students are girls is 0.15.
0.15 simplified in fraction from: 3/20
