Answer:
x = 15
Step-by-step explanation:
In this geometry, x is the geometric mean of the segment lengths of the hypotenuse.
x = √(9×25)
x = 15
Let the equal sides of the isosceles Δ ABC be x.
Given that the perimeter of Δ ABC = 50m.
Therefore, 2x + AC = 50 --- (1)
It is also given that the perimeter of Δ ABD = 40m.
Therefore, x + BD + AD = 40
BD is the median of the Δ ABC. Therefore, D is the midpoint of AC.
So AD = CD.
Or, AD =
AC
Therefore, ![x + BD + \frac{1}{2} AC = 40](https://tex.z-dn.net/?f=x%20%2B%20BD%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20AC%20%3D%2040)
Multiply both sides by 2.
2x + 2BD + AC = 80
From (1), 2x + AC = 50.
Therefore, 2BD + 50 = 80
2BD = 80 - 50
2BD = 30
BD = 15m.

Answer:
15
Step-by-step explanation:
Since we know x = 2 and z = 3x, let's find z by substituting the value for x into z:
z = 3(2) = 6
Now that we have the values of both x and z, we can substitute them into the expression and simplify:
x + 4z - 5 - 3x
= 2 + 4(6) - 5 - 3(2)
= 2 + 24 - 5 - 6
= 15
