Step-by-step explanation:
P+∠L+∠A+∠N=360
o
⇒ 90
o
+∠L+110
o
+85
o
=360
o
⇒ 285
o
+∠L=360
o
∴ ∠L=75
o
⇒ Draw line segment PL=4cm
⇒ Now, take P as center and draw angle of 90
o
.
⇒ Draw 75
o
angle at point L.
⇒ Cut off LA=6.5cm
⇒ Now draw 110
o
from point A.
⇒ Mark point N where the lines from point P and point A intersect .
∴ PLAN is required quadrilateral.

Step-by-step explanation:
a).Answer:- The coordinates of points A and B are (a, 2) and (3, b) respectively, where a and b are constants. The distance AB is ✓(125) units and the gradient of the line AB is 2.
b).Answer:- The coordinate of C is (8,−8).
c).Answer:- Point c is at the distance of 5 units from the y axis along positive x axis and 5 unit from the x axis along the negative y axis.. Point D is at a distance of 6 units from the y axis along positive x-axis. Hence, its abscissa is 6..
Hope its help..
