Step-by-step explanation:
The answer is (-2, -6)
to rotate 90 degrees counterclockwise, you do (-y, x)
Answer: The answer is $152.25
Step-by-step explanation:
First you multiply 0.07 by 163.71 to get 11.4597.
The you subtract 163.71 from 11.4597.
Then that's your answer. I hope this helped!
m_6 + m_8 = 180º because they form a straight line.
So, (2x-5) + (x+5) = 180
3x = 180
x = 60
So, m_115º (2•60 - 5 = 115)
Also, because the two lines are parallel m_6 = m_3 by alternate interior angles.
So, m_3 = 115º
Answer:
(3, - 3)
