Answer: 18°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, the value will equal 90°.
In this question, we've to add both angles and equate them to 90°. This will be:
(2x - 4) + (5x + 17) = 90
2x - 4 + 5x + 17 = 90
Collect like terms
2x + 5x = 90 + 4 - 17
7x = 77
x = 77/7
x = 11
Angle A will be:
= (2x-4)
= 2(11) - 4
= 22 - 4
= 18°
Because of the Absolute Values, when x = -1 or -2, the overall range
is [-1, co)
First convert 14 gallons to grams (52,995.76g), all chemical reactions are related to molecular weights, in this case, 112 atomic weight units for gasoline, 32 for oxygen, 44 for carbon dioxide, and 18 for every mole of octane, 8 moles of CO2 are produced. The proportion will be (52,995.76g x 8 x 44 atomic weight units) / 112 atomic weight units. This equates to 166558.103g. Next, we convert grams to pounds. 367.19776172602 pounds.
