Tthe 2 adjacent angles add up to 109 degrees.
so x + 91 + 101 + x = 180
2x + 192 = 180
2x = -12
x = -6 (answer)
Step-by-step explanation:
<h2>What is the rate of change of the line through (3, -5) and (-5, 3)?..........</h2>
Answer:
Your answer is 12 and -6
Step-by-step explanation:
12 X -6= -72
12 + -6= 6
Answer:
9.6
Step-by-step explanation:
First you figure out that the shadow is 2.5 times larger than what is casting it. Then you divide 24 by 2.5.
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.
Therefore, our variance is 225.
