∠WXY and ∠ZXY are adjacent angles. What equation must always be TRUE? m∠WXY=m∠ZXY m∠WXY+m∠ZXY=90°
m∠WXY+m∠ZXY=180°
m∠WXY+m∠ZXY=m∠WXZ

Pls actually answer and fast

m∠WXY+m∠ZXY=m∠WXZ

Step-by-step explanation:

You don't know the angles to be congruent (equal measures), complementary (measures add to 90 deg), or supplementary (measures add to 180 deg); all you know is that they are adjacent, so the sum of the measures of the two smaller angles equals the measure of the larger outer angle.

m∠WXY+m∠ZXY=m∠WXZ
