Quadrilateral pqrs is inscribed in circle a. which statement is necessarily true? a. m∠r = m∠sb. m∠r + m∠s = 180°c. m∠r = m∠sd. m∠r + m∠s = m∠p + m∠q

(B) m∠R+m∠S=180°

Step-by-step explanation:

The quadrilateral is inscribed in circle A, then m∠R+m∠S=180° as the sum of corresponding angles of a quadrilateral is equal to 180°.

Since, ∠R and ∠S are corresponding angles of the quadrilateral, therefore, they ca't be equal. Hence, ∠R≠∠S.

Also, the sum of all the angles of the quadrilateral is equal to 360°, therefore ∠P+∠Q+∠R+∠S=360°, hence ∠R+∠S≠∠P+∠Q

Therefore, option B is correct.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
