Triangle qrs has the angle measures shown.
m∠q = (1x)°
m∠r = (3x)°
m∠s = (6x)°
the measure of the obtuse angle equals?

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
