I'm sorry, but I have to seriously question the whole process.
-- What does "the angle between the Earth and sun" mean?
-- How in the world does he measure the distance between the Earth and sun ?
-- How are either of these related to the distance between the Moon and Sun ?
To me, this "scientist's" methods are as defective as this question is.
Step-by-step explanation:
Sin(angle) = Opp/Hyp
Sin44 = 10/BC
0.6947 = 10/BC
Cross multiply
BC 0.6947 = 10
Divide both side by 0.6947
BC = 14.39
Answer: a: 4.1x + 29.
Step-by-step explanation:
Since the perimeter is the length of all 3 sides added up, we do:
2.3x + 14 + -0.2x + 15 + 2x = 4.1x + 29
