Sean’s father decided that the number of hours Sean should study daily is equal to the equation y + 4x = 16, where y is the number of study hours and x is the number of relaxation hours. Sean’s mother believes that the number of hours Sean should study daily should be equal to the equation 2y+5x=32. Sean’s parents have decided to use both equations to determine the number of hours Sean should study and relax. What is an equivalent equation to the addition of Sean’s mother’s equation and Sean’s father’s equation? Select all that apply.

Me write an equation for the interior angles of this triangle that uses the triangle sum theorem

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
