False. Supplementary angles have to add up to 180 degrees, and that is clearly not a flat line lol
Answer:
154 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon is 540.
Hence to get the 2 angles,
52+90+90+2n = 540
232 + 2n = 540
2n = 308
n = 154
Answer:
Step-by-step explanation:
Set this up as a proportion
20/8 = 15/vx Cross multiply
20*vx = 8 * 15
20 * vx = 120 Divide by 20
vx = 6
1. A = (1/2)bh = (1/2) * 30 ft * 12 ft = 180 ft^2
2. 21/25 * 100 = 84%
3. $13.26/(3 boxes) = $4.42/box
