Compare and contrast absolute age dating and relative age dating

the answer is a. hope this .

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

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
