Answer:
Its Option C
Step-by-step explanation:
Basically Linear is derived from the word line
Also this an equation for the line
The y-intercept is 8 and the gradient is -7
This is why the function is linear
You can graph the 4 points.
Notice that sides AB and CD are horizontal, so they are parallel with different lengths.
Sides BC and Ad are not parallel.
A quadrilateral with two parallel sides and two non-parallel sides is a trapezoid.
<h2>
Answer:36 
</h2>
Step-by-step explanation:
Given that 
is isosceles triangle.
A isosceles has two sides equal an the third side is the base.
So,
...(i)
Given that length of the base 
Given that the perimeter of the triangle is 
So,
...(ii)
Using (i) and (ii),
<h3>
Answer: D) 72</h3>
======================================
Work Shown:
Angle PQR = (far arc - near arc)/2
2x+72 = ( (2x+252) - (2x+108) )/2
2x+72 = 144/2
2x+72 = 72
2x = 72-72
2x = 0
x = 0/2
x = 0
-------------
Angle PQR = 2x+72
Angle PQR = 2(0)+72
Angle PQR = 72 degrees
