Question

18.6 in

Which is the best approximation for the measure of angle

EGF?

32.8°

40.2

OOO

49.8°

57.2

Answer 1

The answer is "
`40.2^(\circ)`"

Explanation:

Please find the graph file.

Let

`\angle EGF = x\\\\\sin x = (12)/(18.6)\\\\\sin x = 0.6452 \\\\x = \sin^(-1) (0.64516129) \\\\x = 40.1777695^(\circ) \approx 40.2^(\circ)`
