Answer:
axis of symmetry: x= -2
Step-by-step explanation:
axis of symmetry = - (b/2a) ( a is the coefficent of x^2, b is that of x)
so a=1, b=4
- (b/2a) = - (4/2) = -2

Answer:
1. a= 7, A = 49 degrees
Side A = 7 , Side B = 24, Side C = 25
A= 49 degrees, C = 90 degrees , B=41
2. A= 4, B = 6.9, C=8
A= 22 degrees, B = 68, C= 90
3. A= 7, B = 14.4, C=16
A= 45 , B=45 , C=90
