what is the relationship between the horizontal range of a projectile and the impact height, ie the projectile lands below the level it was fired on, i need an equational relationship please and dont give links that i cant open ill give brainliest

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

the answer is 12 as i may remember
