That would be approximately 339638
Answer:
Given - Triangle ABC
AD bisects BC ( I.e AB = AD)
To prove - Angle BAD = Angle CAD
Solution -
AB = AD (given)
Angle B = Angle C ( angle opposite to equal sides are also equal )
In a triangle BAD and CAD
AD = AD ( common)
angle B = Angle C ( prove above)
AB = AD = ( given )
By SAS congruence Triangle ABC is congruent to Triangle ABD
by CPCT BAD = CAD
hence, Proved

Answer:
Step-by-step explanation:
19.
2x^2+x-6=0
x^2+x-12=0
(x+2)(2x-3)=0
x=-2,3/2
20.
x^2+8x+15=0
(x+3)(x+5)=0
x=-3,-5
Answer:
Perimeter of the dog park = 15.4 yards
Step-by-step explanation:
Coordinates of the vertices of the given triangle are,
P(1, 2), Q(1, 6), R(-4, 2)
Since distance between the two points
and
is,
d = 
Length of PQ = 
PQ = 4
Length of PR = 
PR = 5
Length of QR = 
QR = 
= 
= 6.4 yards
Therefore, perimeter of the given triangle = PQ + QR + PR
= 4 + 6.4 + 5
= 15.4 yards
