Hi, Please help me with the 2 questions, will mark and 5 stars and THANKS

C and C

Explanation: C  since both parents contribute 50% of genetic information

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
