That's the second one,
180 - x = r
Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.
The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.
Then that would be 3 and 9.
Answer:
Step-by-step explanation:
Surface Area = 2×(8.25×1.5 + 8.25×3 + 1.5×3) = 83.25 centimeters^2
Answer: D = 40 / C
Step-by-step explanation:
total amount of soil divided by soil in each bag. To find the total amount of soil multiply number of flower boxes (10) by amount of soil each box holds (4 kilograms). So, number of bags (D) equals 40 divided by kg of soil in each bag (C)
