Answer:
18
Step-by-step explanation:
So since the two lines are parallel, 3x is congruent to the angle to the left of 6x+18 and since the two angles together are a straight line it's equal to 180 degrees. So
6x + 18 + 3x = 180
9x + 18 = 180
9x = 162
x = 18
First, we have to calculate the percentage that Sally got in the quiz: 22/40x100%=55%
The percentage of the questions she got wrong: 100%-55%=45%
This is assuming that 40 refers to sides.
Since 40 is an even number, you can have lines of symmetry going from any vertex to the opposite one. Since there can be two identical lines, we just cut in half 40 to 20 so there are no repeats. We can do this for halfway between two vertices as well, so that's another 20. Twenty + 20 = 40 and thus, your answer is 40 lines of symmetry.
Answer: I believe it’s 70
