Recall that the LL theorem, as well as the LA theorem, both apply only to right-triangles.
now, in the LL, if a right-triangle has congruent Legs with another, both right-triangles are congruent.
in the LA, if a right-triangle has one Leg and one Angle congruent with another right-triangle, then they're congruent.
well, in the LA, once you have a Leg and then an Angle touching that Leg, the angle is also touching another Leg, since it is an angle and is cornered by two Legs. The second Leg touched or stemming from that Angle, can only be of one possible length, because the first Leg and the Angle will constrain it to be of certain length.
and that is true for both triangles, and since both triangles will have a second Leg constrained to be a certain length, because of LA, then a second Leg will also be congruent on both right-triangles, so the theorem kinda becomes LAL theorem, Leg Angle Leg, but we can just do away with the Angle part and call it LL.

Answer:
(a) 169
(b) 341
(c) 125
(d) 87
Step-by-step explanation:
Consider the Venn diagram below.
The total number of shoppers surveyed is, <em>N</em> = 428.
Number of shoppers who made a purchase, <em>n</em> (P) = 216
Number of shoppers who were satisfied with the service they received,
<em>n</em> (S) = 294
Number of shoppers who made a purchase but were not satisfied with the service, 
= 47
(a)
The number of shoppers who made a purchase and were satisfied with the service = <em>n</em> (S ∩ P)
(b)
The numbers of shoppers who made a purchase or were satisfied with the service = <em>n</em> (P ∪ S)
(c)
The numbers of shoppers who were satisfied with the service but did not make a purchase = 
(d)
The number of shoppers who were not satisfied and did not make a purchase = 
Whenever you multiply something, you just add it to itself that many times.
ex) 7 × 4 = 7 + 7 + 7 + 7.
Thus n × a = n + n + n + n....a times.
Discriminant D is given by:
D=b²-4ac
Implication of discriminant is as follows:
D<0 two zeros that are complex conjugate
D=0 one real zero of multiplicity 2
D>0 two distinct real zers
D= (+ve perfet square) two distinct rational zeros
From:
12x^2+10x+5=0
plugging in the equation we get:
10²-4×12×5
=100-240
=-140
thus
D<0
