Answer:
30 degrees
Step-by-step explanation:
Let Angle ABC be 2x, Angle EBC be 5x
<span>To find the slope, you divide the difference of the y-coordinates of a point on a line by the difference of the x-coordinates. It is expressed as:
slope = (y2 - y1) / (x2-x1)
slope = 8-(-7) / 4 - 4
slope = 15 / 0
slope = undefined <------ SECOND OPTION
The line should be vertical where the slope is undefined. Hope this answers the question. Have a nice day.</span>
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
