Okay so triangle DEA = 71 degrees
And angle DEB = 90 degrees (right angle)
90 - 71 = 19 degrees
Angle EBA = 90 degrees (right angle)
That leaves the 90 degrees + 19 degrees = 109 degrees
There’s 180 degrees in a triangle so
180 - 109 = 71 degrees

Answer:

y=x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(3-2)/(2-1)

m=1/1

m=1

y-y1=m(x-x1)

y-2=1(x-1)

y-2=x-1

y=x-1+2

y=x+1
