i assuming since Br2 reacts w it that it does not exhibit aromaticity? but it certainly fits Huckel's rule...? OH but i suppose those 4 substituents on the middle ring act as activating groups... that must be it

Better solution than physics galaxy itself No comparison or hate But sir u solved this problem in detail so that an avg student can also understand it In every other places , the solution is a little bit of hard to understand Thank you so much sir❤️
This is awesome, many thanks! φ = 30°; ∆ APO → OPA = 2φ/3; PAO = 3φ → AOP = 7φ/3 → AOB = 14φ/3 → 12φ - 14φ/3 = 22φ/3 arc AB/arc BC = 3/2 → AC = 3k → BC = 2k → 5k = 22φ/3 → k = 22φ/15 → BOC = 2k → BAC = BOC/2 = k = 22φ/15 = 44°

No need all these calculations. Subtract the area of a 3/2 circle of radius 2 from the area of a quarter circle of radius 6. That's it.

I looked at it as 328 being a sum of 3 numbers all power of two. 256, 64 and 8 so 2^8, 2^6 and 2^3 then quickly match a b and c but all as powers of 2 so 1a, 2b and 3c then matching form there as C can only be 1 or 2 etc

Simpler argument not using theorem other than Pythagoras. Let BO = R, the semicircle radius: ACO is a right angled triangle. CO = R - 3. OA = R - 4. AC = 3. So AC² + AO² = CO² (Pythagoras). SO (R-4)² + 3² = (R-3)² and hence R = 8, so area subtraction of the semicircle and circle yields 23π.

Reflect ∆PSQ about QS so that P falls on QR at P'. ∠QPS= ∠QP'S and QP= QP', and P'R= QR-QP' = PS. Hence, ∆SP'R is Isosceles and ∠P'SR = ∠SRP' =θ This implies, ∠QPS= 2θ= ∠QPS In the ∆QPR, 60+θ+2θ=180 θ= 20°

W.L.O.G. Let P = (-1,0), S = (0,0) and R = (1,0). angle(PQR) = theta + (180° - theta - 45°) = 135° Therefore Q lies on intersection of the circle y = sqrt(2 - x^2) - 1 and the line y = -x This solves to: x = 1/2(1-sqrt(3)) , y = 1/2(sqrt(3) - 1) theta = atan( 1/2(sqrt(3) - 1) / (1/2(1-sqrt(3)) - -1) = atan(1/3*sqrt(3)) = 30°
