The teacher will be very surprised to see your correct solution 😉
Divide both parts of the equation by 2
sum
pi asin(3/4) asin(3/4) -- - --------- + --------- 2 2 2
=
pi -- 2
product
/pi asin(3/4)\ asin(3/4) |-- - ---------|*--------- \2 2 / 2
=
(pi - asin(3/4))*asin(3/4) -------------------------- 4
(pi - asin(3/4))*asin(3/4)/4
pi asin(3/4) x1 = -- - --------- 2 2
asin(3/4) x2 = --------- 2
x2 = asin(3/4)/2
