Answer:
Co- interior angles
Step-by-step explanation:
Together they add up to 180°
So angle 5x= 115°
Answer:
10x - 20
Step-by-step explanation:
<em>Distribute 5 </em>to <em>each</em> of the terms within the parentheses to get 5(2x) - 5(4) = 10x - 20.
5x + 6
5x = number of buffets purchased.
6 = 3 * 2 (three friends bought 3 $2 drinks)
m<QRS = 80 degrees.
Supplementary angles = a total of 180 degrees. So if angle ABC = 100, angle QRS would = 80 degrees.
