Is 4xy + 2y = 9 linear ? if yes write the equation in standard form & determine the x & y interests

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

The graph of which equation includes the points (0, 10) and (10, 11)? y = 10x + 11 y = x + 10 y= 1/10x + 10 y = 1/10x + 11

How do i find the missing angle measure in a polygon
