Question

temperature dropped 18 degree celsius in the last 24 days if the rate of temperature drop remains the same how many degrees will the temperature drop in the nexy 18 days?

Answer 1

√AOC + √BOE = 70° (Given)

√BOD =40° (Given)

Find √BOE and reflex √COE

√AOC = √BOD =40° (V.O.A)

√AOC + √BOE =70°

40° + √BOE = 70°

√BOE = 70° - 40°

√BOE = 30°

Reflex √COE = √AOC + √COE + √BOE

√COE + 40° + 30° = 180° [ ∴ √AOB is a straight line ]

√COE + 70° = 180°

√COE =  180° - 70°

√COE = 110°

Reflex √COE = 360° - √COE = 360° - 110° = 250°

Ans. 30° , 250°
