Extra points ! solve the formula for the indicated variable.
t=3u/e for u

U =

Step-by-step explanation:

Given

T =

Multiply both sides by E

ET = 3U ( divide both sides by 3 )

= U

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
