Answer:
31 degrees
Step-by-step explanation:
well each three point of a triangle equals 180
so 20+35= 55 180-55= 125
now if the exterior angle is 156 and it should equal 180 the interior angle would be 24 degrees
now we have 24 and 125 so angle ? = 31
Answer:
y+2=3(x+1)
Step-by-step explanation:
y-(-2)=3(x-(-1))
y+2=3(x+1)
Answer: A. 0.4899 B. 14
Step-by-step explanation:
If X = random variable
then, the standard deviation of the sampling distribution of X = 
A.
GIven: 
The standard deviation of the sampling distribution of X = 
B. Let n be the sample size,

Hence, the required sample size = 14
<h3>

are the slopes of perpendicular lines</h3>
<em><u>Solution:</u></em>
We know that,
Product of slope of a line and slope of line perpendicular to it is always equal to -1
<em><u>Option 1</u></em>


Thus, these are not the slopes of perpendicular lines
<em><u>Option 2</u></em>

This option satisfies the slopes of perpendicular lines
<em><u>Option 3</u></em>

Thus, these are not the slopes of perpendicular lines
<em><u>Option 4</u></em>
2 and 2
Product = 2 x 2 = 4
Thus, these are not the slopes of perpendicular lines
