When table sugar is burned in air, carbon dioxide and water vapor are products, as shown by the following unbalaned chemical equation: c12h22o11(s)+o2(g) =co2(g)+h2o(g)

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

a. is correct
