∡3=142°

Step-by-step explanation:

∠3 and 38° are supplementary angles, which means their sum must equal 180°, therefore, we make an equation and solve for ∡3:

∠3+38°=180°

∡3=142°

So ∡3=142°

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.
