Yogita Ingle 4 years, 9 months ago

Put x = a

x×x+2x+1 = 0

a × a + 2 (a) + 1 = 0

a² + 2a + 1= 0

(a + 1) (a + 1) = 0

a + 1 = 0

a = -1

Prove that sum of all angles of quadrilateral is 360 degree with figure

Posted by Aram Hasan 4 years, 9 months ago

CBSE > Class 09 > Mathematics

1 answers

Yogita Ingle 4 years, 9 months ago

Consider a quadrilateral PQRS.

Join QS.

To prove: ∠P + ∠Q + ∠R + ∠S = 360º

Proof:

Consider triangle PQS, we have,

⇒ ∠P + ∠PQS + ∠PSQ = 180º ... (1) [Using Angle sum property of Triangle]

Similarly, in triangle QRS, we have,

⇒ ∠SQR + ∠R + ∠QSR = 180º ... (2) [Using Angle sum property of Triangle]

On adding (1) and (2), we get

∠P + ∠PQS + ∠PSQ + ∠SQR + ∠R + ∠QSR = 180º + 180º

⇒ ∠P + ∠PQS + ∠SQR + ∠R + ∠QSR + ∠PSQ = 360º

⇒ ∠P + ∠Q + ∠R + ∠S = 360º [Hence proved]

Yogita Ingle 4 years, 9 months ago

The Total surface area of a cone includes the curved surface as well as area of its base, which is given as-

Base Area = πr²

Curved Surface Area = πrl

Thus total surface area is given by-

πr²+ πrl = πr(r + l)
