All of the angles in a triangle must add up to 180. The angle marked 3y can help us find the missing angle of the triangle: 180-3y Then you can make an equation to help solve for y: 50 + (2y-3) + (180-3y) = 180 Combine like terms: 227-y=180 y = 47
Answer <u>(assuming it can be in point-slope form)</u>:
Step-by-step explanation:
With the given information, we can use the point-slope formula, , to write the equation of the line. Substitute values for the , , and in the formula to do so.
The represents the slope, so substitute in its place. The and represent the x and y values of one point the line intersects, so substitute -6 for and -8 for . This gives the following answer and equation (just make sure to convert the double negatives into positives:
