Answer:
X = 108.
Step-by-step explanation:
Heights are equal, So equation will be,
So, solving the eq.
Subtract 4 from both sides ,
Divide 3 to both sides,
Squaring both sides,
Add 8 to both sides,
m^2 -11m -60 = 0
m^2 -11m =60
(m^2 -11m + 121/4) = 361/4
(m - 11/2)^2 = 361/4
m - 11/2 = + or - 19/2
m = 11/2 + 19/2, 11/2 - 19/2
m = 15, -4
---------------------------------------------------
m^2 -11m -60
(11 +- Square root (121 +240))/2
11/2 +- 19/2
m= 15, -4
----------------------------------------------------
m^2 -11m -60
(m - 15) (m + 4)
m = 15, -4
