Two angles are complementary when they add up to 90 degrees<span>
m</span>∠B = 90° - m∠A = 90° - 40° = 50°
Two angles are supplementary when they add up to 180 degrees
m∠C = 180° - m∠B = 180° - 50° = 130°
It would be graph B because it is the only one that is close to it.
If i'm wrong it is ok with me
3(x+2)
Distribute and multiply
3 to x and 2 to get 3x+6
The answer is 3x+6

Answer:
B. 61%
Step-by-step explanation:
When we have the standard deviation of a sample, we use the t-distribution.
The width of an interval is related to the margin of error, which is given by the following equation:
M = T*s
In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.
A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.
So the correct answer is:
B. 61%
