Answer: Sample costs to produce blueberries in the southern San Joaquin Valley ... shape, immediately after planting at a rate of 100 cubic yards per acre to ... most critical period for irrigation goes from fruit expansion (April) through harvest (June). ... The cost of water includes pumping costs of $400 per acre foot or $33.33 per.
X+y=23
X-y=7.4
X+y=23
y=23-X
X-y=7.4
(23-y)-y=7.4
23-2y=7.4
-2y=-15.6
Y=7.8
X+y=23
X+7.8=23
X=15.2
Therefore the two numbers are 7.8 & 15.2
Well there has to be a right angle in there somewhere as the pole must be perpendicular to the ground.
Using the sine rule:
sinA/a = sinB/b where a = 10, A = 90, b = 5√3, B = B
Re-arrange for B, B = arcsin (b(sinA)/a)
B = arcsin(5√3(sin90)/10)
B = 60 degrees.
Answer is C
