Answer:
y=3x^2+12x+13
a=3
b=12
c=13
Step-by-step explanation:
Answer:
b=57° (vertically opposite angles)
Step-by-step explanation:
57°+a+b+c=360° (angles around a point)
57°+57°+a+c=360°
114°+a+c=360°
a+c=360°-114°=246°
a=c (vertically opposite angles)
therefore 2a=246°
a=123°
b=123°
Answer:
This is a right angle shape.
