Answer:
Given:
and
.
Prove: 
Since
, By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly
, it means angles 5, 6, 7 and 8 are 90 degree.
We can say that,
,
,
and 
From figure it is noticed that the angle 1 and 5 are corresponding angles.
If two parallel lines are intersected by a transversal, then the corresponding angles are equal.
Since corresponding angles are congruent, therefore the line must be parallel to each other.
Hence proved that
.
Answer:
if the equation is f(x)=ax^2+bx+c
Step-by-step explanation:
Y-4=3(x+2)
y-4=3x+6
y = 3x +10
so in case of choise C. we get
4 = 3*(-2) +10
4 = -6 +10
4 = 4

Answer:
29 Dodecagon
30 Heptagon
31 Octagon
32 Hexagon
Just divide 360 by the number of sides to find the exterior angles
and 900 by the number of sides for the interior
