ก ñ Given u = W3.-1) and v=(3, 4), what is u. V?
-4/3-3
N
O-4V3+3
O 3V3-4
O 3v3 +4

d is the final answer!

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

thats not a system of equations, that is a solution
