The height is 22 inches? It says it in the question
Answer:
t=-105
Step-by-step explanation:

What we need to do here is to isolate t.
Let's multiply both sides by -15.

7*-15= -105
t=-105
36/7 = 27/x.....36 mm to 7m = 27 mm to x m
cross multiply
(36)(x) = (27)(7)
36x = 189
x = 189/36
x = 5.25 m
Two squares root. Because 3 * 3 = 9 and -3 * -3 = 9.
