Answer : The equation for 'h' is 
Step-by-step explanation :
The given equation is:

Now we have to determine the equation for 'h'.

Multiplying the equation by 2.

on simplifying, we get:

Dividing the equation by 'b'.


or,

Therefore, the equation for 'h' is 
Sum of Interior Angles of any poligon, where n is the number of sides: =
(n-2) × 180°
---------------------
(7 - 2) * 180° =
5 * 180 =
900°
[d]
The answer is b, because u need to use m= y2-y1/x2-x1
