8 and a half
Step-by-step explanation:
you will divide 42 and the 5
Answer:
The value of A is 20
Step-by-step explanation:
To find the answer, note that all triangles have a interior degree measurement of 180. Set the sum of the angles equal to 180.
71x - 1 + 20x + 90 = 180
91x + 89 = 180
91x = 91
x = 1
Now we can use this in the A angle to find the value.
A = 20x
A = 20(1)
A = 20

Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
Answer: graph D
<u>Step-by-step explanation:</u>
graph A) The equation is y = x
graph B) The equation is y = -x² + 2
graph C) The equation is x = y²
graph D) The equation is y = 2
Which equation does not have an "x" in it? <em>D</em>
Therefore, the y-value is not dependent on an x-value.
