The three sides of a triangle are 10,100 and x . Which one of the following is correct ?

The correct answer is B

- In the given figure, PQR is a triangle and quadrilateral ABCD is inscribed in it. QD = 2 cm, QC = 5 cm, CR = 3 cm. BR = 4 cm. PB = 6 cm. PA = 5 cm and AD = 3 cm. What is the area (in cm
^{2}) of the quadrilateral ABCD? - In a given figure, ABCD is a parallelogram, P and Q are the mid points of sides CD and BC respectively. Then the ratio of area of shaded portion: area of unshaded portion is
- If the area of ∆ABC is 30 cm
^{2 }& G is the centroid of ∆ABC.then the area of the ∆ AGB? - In the given figure, ABC is a right angled triangle. ∠ ABC = 90
^{0}and ∠ ACB = 60^{0}. If the radius of the smaller circle is 2 cm, then what is the radius (in cm) of the larger circle? - A solid cylinder has radius of base 14 cm and height 15 cm. 4 identical cylinders are cut from each base as shown in the given figure. Height of small cylinder is 5 cm. What is the total surface area (in cm
^{2}) of the remaining part? - Triangle ABC is similar to triangle PQR and AB : PQ = 2 : 3. AD is the median to the side BC in triangle ABC and PS is the median to the side QR in triangle PQR. What is the value of (BD/QS)
^{2}? - Let two chords AB and AC of the larger circle touch the smaller circle having same centre at X and Y. Then XY = ?
- In the given figure, O is centre of the circle. Circle has 3 tangents. If ∠ QPR = 45
^{0 }, then what is the value (in degrees) of ∠ QOR ? - In a circle two chords AB and CD intersect at O, if AO = 4, BO = 3 and CO is one fourth of OD then Find OD?
- If the ratio of side of a ∆ is 3:4:5, and a ┴ from opposite vertex drawn to the biggest sides at D, if the length of biggest side is 10 then find ratio of ┴ which in drawn at biggest side to AB ?
