Answer:
60° and 120° are supplementary angles. 93° and 87° are supplementary angles.
They are supplementary angles because they form an 180º angle together.
Answer:
14
Step-by-step explanation:
5x + x+96 = 180
6x+96 = 180
6x=84
x= 14

Answer:
The percentage is 83%
Step-by-step explanation:
Generally R-Sq is known as the coefficient of determination and from the question the value is 83% and this R-Sq defines the total variation in test scores can be explained by the linear relationship between years of study and test scores
So 83 % of the total variation in test scores is unexplained by the linear relationship between years of study and test scores
x - 25 = (√x)^2 - 5^2 = (√x - 5)(√x + 5)
Then
(x - 25)/(√x - 5) = √x + 5
and as x approaches 25, we get a limit of √25 + 5 = 5 + 5 = 10.
