Answer:
<u><em>x = 80</em></u>
<u><em>y = 130</em></u>
Step-by-step explanation:
The 2 angles are supplementary. so, x-30 + x+50 = 180.
We solve and get 2x = 180-20
<u><em>x = 80</em></u>
y = x+50, because of parallel rules.
<u><em>y = 130</em></u>

Answer:
Find the area of a cardboard box with a length of 9 inches and a width of 4 inches.
Step-by-step explanation:
9 in × 4 in = 36 in²
To find a perpendicular line, you need to find the negative reciprocal of the slope.
-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.
Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
