Answer:
a) Angle X = 108°
<h3>C). Vertically opposite angles</h3>
as AD is parallel to EH both the angles are equal
The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.
As we now know that the gradient is -1. We can simply put any one point in the equation y - y1 = m(x - x1) to get the line of equation. WHen we calculate the line of equation it come out to be y = -x + 7

Answer: 
Step-by-step explanation:
Since, the quotient of 6 and r = 
The sum of two and the quotient of 6 and r
= 
And, Five-sevenths of the sum of two and the quotient of 6 and r
=
Thus, the required expression is,
The rate of change is 6 secs/foot in terms of seconds per foot.
