\nOP2<\/sup> = OA2<\/sup> + AP2<\/sup>
\n(25)2<\/sup> = OA2<\/sup> + (24)2<\/sup>

\nIf x2<\/sup> + y2<\/sup> = 7xy, then prove that log(\\(\\frac{x+y}{3}\\)) = \\(\\frac{1}{2}\\)
\nGiven x2<\/sup> + y2<\/sup> = 7xy, now add (2xy) on both sides. We get
\nx2<\/sup> + y2<\/sup> + 2xy = 7xy + 2xy = 9xy
\nConsidering square root on both sides we get
\n\\(\\sqrt{x^2+y^2+2 x y}\\) = \\(\\sqrt{9 x y}\\)
\nx + y = 3\\(\\sqrt{x y}\\)
\n\u21d2 \\(\\frac{x+y}{3}\\) = \\(\\sqrt{x y}=(x y)^{\\frac{1}{2}}\\) considering logarithm on both sides, we get
\nlog(\\(\\frac{x+y}{3}\\)) = log\\((x y)^{\\frac{1}{2}}\\) = \\(\\frac{1}{2}\\) log(xy)
\nlog(\\(\\frac{x+y}{3}\\)) = \\(\\frac{1}{2}\\) (log x + log y) (\u2235 log mn = log m + log n)<\/p>\n
\n“If we multiply or divide both sides of a linear equation by a non-zero number, then the roots of that linear equation will remain the same.”
\nIs it true ? If so, justify with an example.
\nSolution:
\nGiven statement : “If we multiply or divide both sides of a linear equation by a non-zero number, then the roots of that linear equation will remain the same”.
\nConsider a linear equation
\nx + y = 5 ………….. (1)
\nOne of the solutions for this equation (1) is (2, 3)
\nNow multiply equation (1) by ‘3’.
\n3 (x + y) = 3 \u00d7 5
\n3x + 3y = 15 ………….. (2)
\nNow substitute the point (2, 3) in the equation (2).
\n\u2234 3(2)+ 3 (3) = 15
\n16 + 9= 15 \u21d2 15 = 15
\n\u2234 (2, 3) is also a solution for the equation (2).
\nSo the given statement is true.<\/p>\n
\nMeasures of sides of a triangle are in Arithmetic Progression. Its perimeter is 30cm, and the difference between the longest and shortest side is 4cm; then find the measures of the sides.
\nSolution:
\nLet the 3 sides of given triangle = a – d, a, a + d
\nThen its perimeter
\n= a – d + a + a + d = 30 cm.
\n3a = 30 cm \u21d2 a = \\(\\frac{30}{3}\\) = 10 cm.
\nThe larger side = a + d
\nThe shorter side = a – d
\nThe difference between the above two
\n= (a + d) – (a – d) = 4 cm.
\na + d – a + d = 4 cm.
\n2d = 40 \u21d2 d = \\(\\frac{4}{2}\\) = 2 cm.
\na = 10 cm, d = 2 cm
\nSo the sides a – d = 10 – 2 = 8 cm
\nand a + d=10 + 2 = 12 cm.
\nSo 8, 10, 12 cm are the sides of the triangle.<\/p>\n

\n(\u2235 sin2<\/sup> \u03b8 + cos2<\/sup> \u03b8 = 1)<\/p>\n
\nNow given cot \u03b8 = \\(\\frac{7}{8}\\)) then we have
\n(1 + cot2<\/sup> \u03b8) = cosec2<\/sup> \u03b8
\n\u21d2 1 + (\\(\\frac{7}{8}\\))2<\/sup>
\n= 1 + \\(\\frac{49}{64}\\) + \\(\\frac{64+49}{64}\\) = \\(\\frac{113}{64}\\)
\n\u2234 cosec \u03b8 = \\(\\sqrt{\\frac{113}{64}}\\)
\n\u2234 \\(\\frac{1+\\cos \\theta}{\\sin \\theta}\\) = cosec \u03b8 + cot \u03b8
\n= \\(\\frac{\\sqrt{113}}{8}\\) + \\(\\frac{7}{8}\\) = \\(\\frac{7+\\sqrt{113}}{8}\\)<\/p>\n

\nSolution:
\nLet the speed of the slower train = x kmph
\nthen speed of the faster train = x + 5 kmph.
\n
\nDistance = Speed \u00d7 Time
\n\u2234 Distance travelled by the first train = 2(x + 5) = 2x+ 10

\n\u2234 x – 15 = 0 (or) x + 20 = 0
\n\u21d2 x = 15 (or) -20
\nBut x can’t be negative.
\n\u2234 Speed of the slower train x = 15kmph.

\nA) Show that \u221a5 – \u221a3 is an irrational number.
\nSolution:
\nSuppose \u221a5 – \u221a3 is not an irrational number. \u221a5 – \u221a3 is a rational number.
\nLet \u221a5 – \u221a3 = \\(\\frac{p}{q}\\) where q \u2260 0 and p, q e \u2208 Z squaring on both sides
\n5 + 3 – \\(2 \\sqrt{15}=\\frac{p^2}{q^2}\\)
\n\\(\\sqrt{15}=\\frac{8 q^2-p^2}{2 q^2}\\)
\n\u2234 p, q \u2208 Z & q \u2260 0
\n8q2<\/sup> – p2<\/sup> & 2q2<\/sup> \u2208 Z and also 2q2<\/sup> \u2260 0.
\nSo \\(\\frac{8 q^2-p^2}{2 q^2}\\) JL is a rational number.
\nbut \\(\\sqrt{15}\\) is an irrational number.
\nAn irrational number never be equal to a rational number.
\nSo our supposition that \u221a5 – \u221a3 is not an irrational number is false.
\n\u2234 \u221a5 – \u221a3 is an irrational number.<\/p>\n

\nA) Construct a triangle of sides 4.2 cm, 5.1 cm and 6 cm. Then construct a triangle similar to it, whose sides are 2\/3 of corresponding sides of the first triangle.
\nSolution:
\n
\nConstruction Steps :<\/p>\n\n
\nSolution:
\nTo begin let us consider a circle with centre ‘O’ and radius 6 cm.
\nLet PA and PB are two tangents draw from a point ‘P’ outside the circle and the angle between them is 60\u00b0.
\nIn this \u2220APB = 60\u00b0. Join OP.
\n
\nAs we know, OP is the bisector of \u2220APB, then
\n\u2220OAP = \u2220OPB = \\(\\frac{60^{\\circ}}{2}\\) = 30\u00b0 (\u2235 \u0394OAP\u2245\u0394OBP)
\nNow in \u0394OAP
\nsin 30\u00b0 = \\(\\frac{\\text { Opposite side }}{\\text { Hypotenuse }}=\\frac{\\mathrm{OA}}{\\mathrm{OP}}\\)
\n\\(\\frac{1}{2}=\\frac{6}{\\mathrm{OP}}\\) (From trigonometric ratio)
\nOP = 12 cm
\nNow we can draw a circle of radius 6 cm with centre ‘O’. We then mark a point at a distance of 12 cm from the centre of the circle. Join OP and complete the construction.
\n
\nHence PA and PB are the required pair of tangents to the given circle.<\/p>\n\n
