Can u me figure out the reasoning for the answer ?

In a 30-60-90  triangle the side opposite the 30 degree angle is half the length of the hypotenuse. 
XZ = XY/2 = 4/2 = 2

By the Pythagorean theorem:
YZ = √(4² - 1²) = √(16-4) = √12 = 2√3

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side: 
tan(Y) = XZ/YZ =2/2√3 = 1/√3 = √3/3

Answer is B. √3/3

4038 is the answer lol just use a calculator

0=6x+2y+10 is equivalent to the simplified form: y= -3x - 5• parallel lines always have the same slope, different y intercept knowing this, we can say the slope, or m of the line parallel to y= -3x - 5 is -3.m= -3 hope this could !
