d=discount tickets
f=full price tickets
d=f+180 (180 more full price tickets than discount tickets)
f+d=240
i think it's 118 i don't know because I studied this 4 years ago
We are given with the equation
1/sin 18 - 1/sin 54 = 2
We are meant to verify if the equation is true
So,
(sin 54 - sin 18)/ sin 18 sin 54 = 2
sin 54 - sin 18 = 2 sin 18 sin 54
sin 18*3 - sin 18 = 2 sin 18 sin 18*3
Use trigonometric identities to verify the equation.
The identities to use are the double and product of angles.<span />
Answer: yes because angles 3 and 7 are congruent
