Answer:
z = -12
Step-by-step explanation:
Rewritting the equations, we have:
x + y = xy (eq1)
2x + 2z = xz (eq2)
3y + 3z = yz (eq3)
From the first equation:
x = y/(y-1) (eq4)
From the third equation:
y = 3z/(z - 3) (eq5)
Using the value of y from (eq5) in (eq4), we have:
x = [3z/(z - 3)] / [3z/(z - 3) - 1]
x = [3z/(z - 3)] / [(3z - z + 3)/(z - 3)]
x = 3z / (2z + 3) (eq6)
Using the value of x from (eq6) in (eq2), we have:
6z / (2z + 3) + 2z = (3z / (2z + 3))*z
(6z + 4z^2 + 6z) / (2z + 3) = 3z^2 / (2z + 3)
12z + 4z^2 = 3z^2
z^2 = -12z
z = -12
18.8 + 77.2 = 96?

Answer:
Perimeter of is .
Explanation:
Given: In , , and AD= 8cm.
In
Sum of the measure of the angles of triangles is 180 degree.
or
Simplify:
∵ AD= 8cm and to calculate the length of CD we use tangent ratio i.e,
then;
or
Simplify:
cm.
Also, find the length of AC, we use sine ratio i.e, .
Then,
or
On simplify:
cm.
Now, in triangle ABC;
, then
[Sum of the measure of the angles in the triangle is 180 degree]
To calculate the length of BC;
[∴ ]
therefore,
or
Simplify:
cm.
Using Pythagoras theorem in triangle ACB;
Let BD be x cm
AB = 8+x cm , AC = 16 cm and cm
or
or
Simplify:
x=24 cm
Therefore, the length of AB = 8+x= 8+24=32 cm
Perimeter(P) of triangle ABC is equal to the sum of the sides of the triangle.
⇒ P= AB+BC+AC = cm
