Answer:

y = -3x + 11.

Step-by-step explanation:

The slope of the given line segment is (3-7)/(-4-8) = -4/-12 = 1/3.

The midpoint of the line has coordinates (8-4)/2, (7+3)/2.

= (2, 5).

The slope of the perpendicular bisector = -1/ 1/3 = -3.

So it's bisector has equation:

y - y1 = m(x - x1)=

y - 5 = -3(x - 2)

y = -3x + 6 + 5

y = -3x + 11.

The given Angles (4x + 2) and (3x + 3) are forming linear pair, so

$4x + 2 + 3x + 3 = 180$

$7x + 5 = 180$

$7x = 180 - 5$

$7x = 175$

$x = \dfrac{175}{7}$

$x = 25$

now, let's find Angle DCB :

$3x + 3$

$(3 \times 25) + 3$

$75 + 3$

$78 \degree$

If a+b+c=0 for a,b,c then prove a²/bc+b²/ca+c²/ab=3.

Ierofanga [76]

According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in all the fraction then you get
a²/bc+b²/ca+c²/ab=3.
hence proved
