A laser beam travels from a telescope on Earth to a Moon and then back to the Based on this information , how far is the Moon Earth? PLEASE HELP? A. 384,000,000

B. 58.600, 000m;

C. 1, 536, 000, 000m

D. 117, 000, 000m

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
