SCHOOL‚ THANE. 2012-13 WORKSHEET :10 TOPIC: CIRCLES&TANGENTS SUB: MATHEMATICS. STD: X 1. Three circles are described touching each other at two places externally. If the sides of the triangle are 4cm‚ 6 cm and 8 cm‚ find the radii of circles. 2. In the given figure‚ circles with centres O and O’ touch internally at point A. AB is a chord of bigger circle intersecting the smaller one at C. If the smaller circle passes through the centre of the bigger circle ‚ then P.T AC = CB. B A A O b

When we first checked our agar dish on February 15‚ 2010 we noticed two circles for the zone of inhibition the small circle was 1.5 cm and the medium circle was 3.00 cm. Two days later when we checked it again the small circle had stayed the same at 1.5 cm but the medium circle was 3.02 cm. The changes were minimal during that first week. Week two however on February 24‚ 2010 the small circle had become smaller it was now 1.3 cm and the

of two sides is greater of the third side and the difference of two sides is smaller than the third one. Each bisector‚ altitude and angular bisector of a side is coincident. Equilateral triangle is a symmetrical figure and it has three symmetric axes‚ each bisector‚ altitude and angular bisector of a side locates in the symmetric axes. The circumcenter‚ incenter‚ orthocenter and center of gravity are the center of circle. 3. Isosceles Triangle A triangle has two congruent sides and two base angles

The free surface was also seen. Next was simple columnar epithelium looked like small circles also inside of a big circle and in each circle were one dot which was

yellow and white fur with black circles. It helps them blend in with their natural surroundings and help it to capture prey.They have powerful legs‚ along with huge leapers allowing them to jump as high as 50 feet. Their paws acts as snowshoes and keeps them from sinking into the snow. As long as their tails are‚ they use them to cover sensitive body parts against the cold. Even though the Snow Leopard can kill three times their size‚ they are known for eating smaller animals such as rodents and game

Week Seven Practical Problem In this assignment‚ you examine a process that links polygons and circles. You will reach some quantitative conclusions about their respective areas and the relationship between the two. As you know‚ a regular polygon has sides of equal length and angles that are the same. This confers a high degree of symmetry to these figures. A circle may be thought of as the logical limit of an n-sided polygon as n goes to infinity; the sides become infinitesimally small‚ and

ABSTRACT Mobile positioning technology has become an important area of research‚ for emergency as well as for commercial services. Mobile positioning in cellular networks will provide several services such as‚ locating stolen mobiles‚ emergency calls‚ different billing tariffs depending on where the call is originated‚ and methods to predict the user movement inside a region. The evolution to location-dependent services and applications in wireless systems continues to require the development of

How professional marketers manipulate customers into buying more than they really need? Person 1: Let me begin with a simple example: If given these 3 options‚ which option would you most likely choose? * Coke - 12k * Burger - 22k * Burger + Coke - 22k Most people would skip the burger-only option and also skip the coke-only option and go for the burger-and-coke option‚ right? Who would want to buy the Burger option alone when both the burger and coke option is offered for the same
