Answer 1

$\huge\underline\mathcal{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

• Given - a circle along with the measure of two angles at the centre

• To calculate - measure of angle JGH

We know that ,

the sum of all the angles at the centre or the sum of all the central angles of a circle equals 360°

$\therefore \: \angle \: IGJ \: + \: \angle \: IGH \: + \: \angle \: JGH = 360\degree \: \\ \\ \implies \: 125\degree + 149\degree + \angle \: JGH = 360\degree \\ \\ \implies \: 274\degree + \angle \: JGH = 360\degree \\ \\ \implies \: \angle \: JGH = 360\degree - 274\degree \\ \\ \implies \: \angle \: JGH = 86\degree$

therefore , option ( c ) 86° is correct
