the answer is the first one
Answer:
xw= 60°
ym=60°
mw=120°
Step-by-step explanation:
Angles on a straight line add up to 180°. Therefore 180-78+42°=60°
Opposite angles are equal. Therefore 60°=60°
Angles in a circle = 360° Therefore 78°+42°+60°+60°+120°=360°
y+4=-2(x+1)
y-y1=m(x-x1)
y-(-4)=-2(x-(-1))
100 im pretty sure because 10 x 10 = 100
