A.
Getting an exact number for gravel is difficult because it spills and the ground is not usually perfectly level. Thus it would be okay to estimate the amount needed.
If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.
the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130
Hope this helps!
You would use the SSS, ASA, AAS, RHS theorems to prove two triangles to be congruent.
Answer:

Step-by-step explanation:
equations:
35 + 30x = 55 + 20x
-35 -35
30x = 20 + 20x
-20x -20x
10x = 20
/10 /10
x = 2
Ignore the height (3) and concentrate on the length and width of the bottom:
The bottom is 15 cm by 3 cm, and so the diagonal of the bottom is
sqrt(15^2 + 3^2) = sqrt(225+9) = sqrt(334).
