True because i² = -1 and a and b are real
All angles of a triangle have to equal 180 degrees. The top and bottom triangle are the same. So the first angle tells you 32 degrees. The second one has a little square which means 90 degrees. So 180 - 32 - 90 = 58.
So the angle A is 58. Since the top triangle and bottom triangle have the same angle measurement then angle C = 58 degrees.
Answer:
at first we put the numbers in order from least to greatest
2 , 6 , 6 , 7 , 8 , 9
1st quartile = 6
median = (6+7)/2 = 6.5
3rd quartile = 8
989.5 divided by 17.8 is 55.5898876404
so about 55 ish
I think that's right but I'm not sure :)
