Answer:
x = 12 or 
Step-by-step explanation:
Find the length of x for one side of the triangle first. To do this, use the Pythagorean Theorem which states: a² + b² = c² or in this case c² - a² = b². c² is 45 and a² is 3*3 or 9. Subtract 45-9 to get 36. Find the square root of 36 to get 6. The opposite side is also going to have a missing side length of 6 so add 6+6 to get 12 as x.
Hope it helps!
Answer:
A triangle is 180 degrees. Imagine that two angles would be given as maybe 89 and 30 degrees. With these two angles already given you can find the last third angle by adding the 2 given angles and subtracting it from 180. There fore it would look like 180-119=61. 61 would be your unknown angle degree.

90 heads in 100 tosses.
Answer: There isn’t sufficient evidence to support this
claim, because the coin is a fair coin.
Given claim: Movie patrons have IQ scores with a standard
deviation that is less than the standard deviation of 15 for the general
population. A simple random sample of 40 movie patrons result in IQ scores with
a standard deviation of 14.8.
Answer: Claim is either true or false
