In order to find the missing number use the Pythagorean theorem which is used to find a missing length of a right triangle. The formula is a 2 + b 2 = c 2, where a and b are the legs of the triangle, and c is the hypotenuse. So the answer would be 22squared plus 27squared which will equal....
Answer:
Option B. is correct
Step-by-step explanation:
Given: The regression equation is y = 1.73 x + 0.39
To find: number of representatives for Oregon, which has a population of about 3.3 million
Solution:
The regression equation determined the specific relationship between a dependent variable and one or more independent variables.
To find number of representatives for Oregon, which has a population of about 3.3 million, put 
in the regression equation is y = 1.73 x + 0.39
So, 6 representatives for Oregon has a population of about 3.3 million
Option B. is correct
Answer:
<em>The measure of the angles is 45° and 135°</em>
Step-by-step explanation:
When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.
Let's call x and y the two required angles. Knowing they form a linear pair:
x+y=180
We also know one angle is 1/3 of the other angle, thus:
x=y/3
Or, equivalently:
3x=y
Substituting y into the first equation:
x+3x=180
Simplifying:
4x=180
Solving:
x=180/4=45
The other angle is:
y=3x=3\cdot 45=135
Thus the measure of the angles is 45° and 135°
