The following is an example of reasoning: In your study of geometry, in every triangle you have seen the sum of all three angles equals 180. You conclude that this is true in all cases.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

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.
