And include explanation if possible

Left side angle = 180-150-12 = 18 degrees

10 / sin 12 = c / sin 18

c = 10 * sin 18 / sin 12

c = 14.9 cm to nearest tenth

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
