Andrea, Belinda and Chloe spent the evening with their husbands. Eugene was seen with his wife dining at Stake Out but they were

not the couple that went off in a limousine. Belinda went to see Rainbo IV but not with David. Andrea and her husband travelled by taxi and it was neither Flavian nor Eugene who was seen with his wife on a tandem bike. Who was it then that spent their evening at Water World fun park, and how did they get there?

We can solve the puzzle by simplifying the conditions in the table below:

Husband                         Wife                      Place Visited                      Means
Eugene                        Chloe                       Stake Out                  not Limousine
not David, then Flavian Belinda                     Rainbo IV               then Limousine
then David                    Andrea     then Water World fun park               Taxi

Therefore, from the given conditions, David and Andrea spent their evening at Water World fun park and they got there by taxi.

Answer:

PQ = PM\cos MPQ + MQ\cos MQP=2PM\cos MQP

Step-by-step explanation:

given MQR = 60, PQR = 75

MQP = 75 -60= 15QR = ((18(1+\cos 30))^{2}-(2\cos 15)^{2})^{\frac{1}{2}}

WE KNOW THAT MQR +QRM +QMR = 180

MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL

THEREFORE QMR = 90 - 60 = 30

therefore PQM = 75 - 60 = 15

PM = PQ because M is the mid point

therefore PR = PM + MQ\cos QMR

                PR = 18(1+\cos 30)

QR = (PR^{2}-PQ^{2}))^{\frac{1}{2}}

PQ = PM\cos MPQ + MQ\cos MQP=2PM\cos MQP

x^{2} -2x-15=0
P(-15)
s(-2)
x^{2} -5x+3x-15
=x(x-5)+3(x-5)
=(x+3)(x-5)
x=5
