Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Slope of line passing through points\u00a0(2,1) and (6,\u00ad3)<\/p>\n

= $\\frac{3 – 1}{6 – 2} = \\frac{2}{4} = \\frac{1}{2}$<\/p>\n

Slope of two parallel lines is always equal.<\/p>\n

=> Slope of the line parallel to the line having slope 1\/2 = $\\frac{1}{2}$<\/p>\n

=> Ans – (A)<\/p>\n

2)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

slope = $\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\\frac{2+3}{5-x}=\\frac{5}{5-x}=\\frac{-2}{3}$<\/p>\n

$\\rightarrow 15 = -10 + 2x$<\/p>\n

$\\rightarrow x = \\frac{25}{2} = 12.5$<\/p>\n

so the answer is option C.<\/p>\n

3)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

slope m = $\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\\frac{2+2}{4-3}=4$<\/p>\n

slope of the perpendicular line = -1\/m = -1\/4.<\/p>\n

So the answer is option D.<\/p>\n

4)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Slope of the two lines, $m_1=1$ and $m_2=\\frac{1}{\\sqrt{3}}$<\/p>\n

Let angle between them = $\\theta$<\/p>\n

Then, $tan(\\theta)=|\\frac{m_1-m_2}{1+m_1m_2}|$<\/p>\n

=> $tan(\\theta) = \\frac{1-\\frac{1}{\\sqrt{3}}}{1+\\frac{1}{\\sqrt{3}}}$<\/p>\n

=> $tan(\\theta)=\\frac{tan(45)-tan(30)}{1+tan(45)tan(30)}$<\/p>\n

=> $tan(\\theta)=tan(45-30)$ \u00a0 \u00a0 \u00a0$\\because [tan(A-B)=\\frac{tanA-tanB}{1+tanAtanB}]$<\/p>\n

=> $\\theta = 15$\u00b0<\/p>\n

=> Ans – (A)<\/p>\n

5)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

Let ‘a’ be the length of side of the hexagon. Therefore, the area of hexagon = $6*\\dfrac{\\sqrt{3}}{4}\\times a^2$.<\/p>\n

The area of triangle PQR = $\\dfrac{\\sqrt{3}}{4}\\times (a\/2)^2$<\/p>\n

Therefore, the are of the shaded region = $6*\\dfrac{\\sqrt{3}}{4}\\times a^2$ – $\\dfrac{\\sqrt{3}}{4}\\times (a\/2)^2$ = $\\dfrac{23\\sqrt{3}a^2}{16} = X$<\/p>\n

$\\Rightarrow$ $a^2 = \\dfrac{16X}{23\\sqrt{3}}$<\/p>\n

The area of the circle = $\\pi*a^2$<\/p>\n

$\\Rightarrow$ $\\dfrac{16 \\pi}{23 \\sqrt{3}}$ X. Hence, option A is the correct answer.<\/p>\n

6)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let us assume that ‘a’ is the length of the side of equal sides of the isosceles triangle.<\/p>\n

<\/figure>\n

We can see that $a+\\sqrt{2}*a+a=2$<\/p>\n

$\\Rightarrow$ a = $\\dfrac{2}{2+\\sqrt{2}}$<\/p>\n

Therefore, the perimeter of the regular octagon = $8*a*\\sqrt{2}$<\/p>\n

$\\Rightarrow$\u00a0$\\dfrac{8\\sqrt{2}*2}{2+\\sqrt{2}}$<\/p>\n

$\\Rightarrow$\u00a0$\\dfrac{16}{1+\\sqrt{2}}$ … (1)<\/p>\n

Area of regular octagon = $2x^2(1+\\sqrt{2})$ where ‘x’ is the length of each side.<\/p>\n

Here, x = $a\\sqrt{2}$ = $\\dfrac{2\\sqrt{2}}{2+\\sqrt{2}}$ =\u00a0$\\dfrac{2}{1+\\sqrt{2}}$<\/p>\n

Therefore, area of the regular octagon = $2*(\\dfrac{2}{1+\\sqrt{2}})^2(1+\\sqrt{2})$ = $\\dfrac{8}{1+\\sqrt{2}}$ =$\\dfrac{8}{1+\\sqrt{2}}*\\dfrac{1+\\sqrt{2}}{1+\\sqrt{2}}$ = $\\dfrac{8*(1+\\sqrt{2})}{3+2\\sqrt{2}}$<\/p>\n

Hence, we can say that none of the given answer is correct.<\/p>\n

7)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

AB = 54 cm and $\\triangle$ANM ,\u00a0$\\triangle$OCP ,\u00a0$\\triangle$OPX are equilateral triangles.<\/p>\n

=> MN = MR = NO = OP = PQ = QR = $\\frac{54}{3} = 18$ cm<\/p>\n

Thus,\u00a0\u00a0MNOPQRM is a regular hexagon with side 18 cm<\/p>\n

$\\therefore$ Area of\u00a0\u00a0MNOPQRM = $\\frac{3 \\sqrt{3}}{2} (side)^2$<\/p>\n

= $\\frac{3 \\sqrt{3}}{2} \\times 18^2 = 486 \\sqrt{3} cm^2$<\/p>\n

8)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

<\/figure>\n

If a point is equidistant from all 3 vertices, it has to be the circumcentre. The given circle with centre S is concentric and touches two sides.<\/p>\n

As S is equidistant from 2 of the sides (say AB and AC), => It lies on angle bisector of $\\angle A$.<\/p>\n

=> $\\triangle ABC$ is isosceles with AB = AC<\/p>\n

Radius of the circle = RS = SQ = 175 cm and SA = SB = SC = 625 cm<\/p>\n

=> $AR = \\sqrt{625^2 – 175^2} = 600$<\/p>\n

Let SP = x<\/p>\n

=> $(BP)^2 = (BA)^2 – (AP)^2 = (BS)^2 – (SP)^2$<\/p>\n

=> $1200^2 – (625 + x)^2 = 625^2 – x^2$<\/p>\n

=>$1200^2 – 625^2 – x^2 – 2*625x = 625^2 – x^2$<\/p>\n

=> $1200^2 – 2 * 625^2 = 1250x$<\/p>\n

=> $x = \\frac{658750}{1250} = 527$<\/p>\n

=> $BP = \\sqrt{625^2 – 527^2} = 336$<\/p>\n

$\\therefore$ ar $(\\triangle ABC)$ = $\\triangle ASB + \\triangle ASC + \\triangle SBC$<\/p>\n

= $(600 \\times 175) + (600 \\times 175) + (527 \\times 336)$<\/p>\n

= $105000 + 105000 + 177072 = 387072$<\/p>\n

9)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

According to given dimensions, triangle will be a right angled triangle.
\nSo BC = 12
\nAnd area = $\\frac{1}{2} \\times 12 \\times 5$
\n= 30<\/p>\n

10)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

<\/figure>\n

Using distance formula,<\/p>\n

$CX = \\sqrt{(17.5 – 5.5)^2 + (23.5 – 7.5)^2} = \\sqrt{12^2 + 16^2}$<\/p>\n

= $\\sqrt{144 + 256} = \\sqrt{400} = 20$<\/p>\n

=> $AC = 2 \\times CX = 40$<\/p>\n

$BX = \\sqrt{(17.5 – 13.5)^2 + (23.5 – 16)^2} = \\sqrt{4^2 + 7.5^2}$<\/p>\n

= $\\sqrt{16 + 56.25} = \\sqrt{72.25} = 8.5$<\/p>\n

=> $BD = 2 \\times BX = 17$<\/p>\n
