Show that the equation x^(2)-6xy+5y^(2)+10x-14y+9=0 represents a pair of lines. Find the acute angle between them. Also find the point of intersection of the lines.

For the straight line 4x + 3y - 6 = 0 and 5x + 12y + 9 = 0 , find the equation of the bisector of the obtuse angle between them.

The given pie Chart (angles are not as per chosen scale) presents the marks scored by Amit in five subjects. Maximum marks in each subject = 100 Total score of Amit = 450 दिया गया वृत्त-आरेख ( कोण किसी चयनित पैमाने के अनुसार नहीं हैं ) पांच विषयों में अमित के द्वारा प्राप्त किये गए अंकों को दर्शाता है | प्रत्येक विषय के अधिकतम अंक = 100 अमित का कुल प्राप्तांक =450 What is the difference between the marks scored by Amit in Hindi and Maths? अमित के द्वारा हिंदी और गणित में प्राप्त किये गए अंकों में क्या अंतर है?

In angle PQR,PQ =6 cm , PR =9cm and M is a point on QR such that it divides QR in the ratio 1: 2 PM bot QR . Find QR.

In the figure, line AB||line CD|| line EF, line l and line m are its transversals. If AC = 6, CE = 9, BD = 8 then complete the following activity to find DF. Activity : line AB|| line CD|| line EF and line l and m are the transversals. (AC)/(square) = (square)/(DF) ..[Property of three parallel lines and their transversals] :. (6)/(9) = (square)/(DF) DF = square
