You roll a pair of dice and can see the sum is either 7 or 8. What is the conditional probability the sum is 7 given that it is 7 or 8?

e) none of the above because the measure of angle cba is 101°

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.
