Hello! every triangle’s interior angles add up to 180. here would be how I solve this equation.
180-75-40=65 (find missing angle)
65+x=180 (supplementary angles)
180-65=x (substitution)
115=x (simplify)
x=115 (reflexive property of equality)
If i'm correct, the answer should be
-3a
hope this helped! 8)

If you had an equation such as 50%x=20, I would convert the percent to a decimal first. So, 0.50x=20. Then I would change the decimal into a simplified fraction. In this case it is 1/2. So, 1/2x=20. Then I would reciprocate the fraction and multiply that by 20. So x=20*2/1. From this, we would get x=40/1, but the 1 is not necessary, so we can write the final answer as x=40.
Biased is like the resuls are not representative of the whole, you asked a group strongly for a certain think
like if you wanted to see how many people want to keep the gym, a biased example would be if you went to the gym becasuse they are all exercising and like exercising, therefor want the gym to stay
biased normally means the person who is doing the survey picks specific people that they know will vote for them
A. not random, these people are picked (she could pick 5 of her friends)
B. random so not biased, but more spread than A
C. also random
A is llikely biased
