Answer:
Friend is not correct.
Step-by-step explanation:
<em>The complete question with image is attached.</em>
We need to find the angle and the point (0.8), or the angle created between the two lines.
First we need to find slope (m) of both the lines.
The slope (m) is change in y coordinates divided by change in x coordinates. Or
<u>Slope of line above:</u>
<u>Slope of below line:</u>
The formula to find angle between two lines is:
Where m_1 = -2 and m_2 = 2
Plugging in the values, we get:
Angle = 53
Hence, your friend IS NOT correct.
Answer:
2a +2b +4
Step-by-step explanation:
The perimeter is the sum of the lengths of the three sides. If x represents the length of the third side, then ...
(3a +8) +(5a +b) +x = (10a +3b +12)
Subtracting from the equation everything on the left side that is not x, we get ...
x = (10a +3b +12) -(3a +8) -(5a +b)
= a(10 -3 -5) +b(3 -1) +(12 -8)
= 2a +2b +4
The length of the third side is 2a +2b +4.
