try asking your teacher.
Answer: In the figure AB is about 8.4 inches and AC is about 13.05 inches.
Step-by-step explanation: We can use cosine to find the hypotenuse. 
Using a calculator x is about 13.05
Using tangent we can find the length opposite of <C

Using a calculator x would be about 8.4
9x-7=-7
9x=o
x=0
so the answer....is 0
<span>In 10 repetitions, there was an instance where 3 or more out of 5 free throw missed. So the probability of her missing 3 or more out of 5 free throw is 0/10=0% or 0.0%. I</span>t appears that your answer of 0% is correct given your experiment.
The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
