a group of 20 children. Boys Girls Left-handed 3 N Right-handed co 9 o A child is chosen at random from the group. a) What is the probability that the chosen child is a girl? Give your answer as a fraction. b) What is the probability that the chosen child is a left-handed girl? Give your answer as a fraction

(23*2)-12=x     x=34

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.
