m∠1 = 70 degrees

Step-by-step explanation:

Let's extend line t to line q such that it forms a mini triangle of a sort. Now the 134 degree angle formed lays on a line segment so that the other, adjacent angle formed should be: 180 - 134 = 46. And, the 116 degree angle formed lays on a line segment so that the other, adjacent angle formed through the extension of line t is: 180 - 116 = 64. Now the "mini triangle" only has one angle left to be computed, and knowing the other two angles to be 46 degrees and 64 degrees the angle is: 180 - 64 - 46 = 70 (as a triangle has a total of 180 degrees). The angle that we just calculated should act as a corresponding angle to angle 1 (what we want to calculate) so that they area congruent, and the m∠1 = 70 degrees

Hope you have a vivid enough imagination to understand this!

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
