Ques. 4 of exercise 10.6 maths ncert class 9 |
| Answer» Vertex B of ABC is located outside the circle with centre O.Side AB intersects chord CE at point E and side BC intersects chord AD at point D with the circle.We have to prove thatABC = [AOC – DOE]Join OA, OC, OE and OD.Now AOC = 2AEC[Angle subtended by an arc at the centre of the circle is twice the angle subtended by the same arc at any point in the alternate segment of the circle]AOC = AEC …(i)Similarly DOE = DCE ….(ii)Subtracting eq. (ii) from eq. (i),[AOC – DOE] = AEC – DCE ….(iii)Now AEC = ADC[Angles in same segment in circle] ….(iv)Also DCE = DAE[Angles in same segment in circle] ….(v)Using eq. (iv) and (v) in eq. (iii),[AOC – DOE]= DAE + ABD – DAE[AOC – DOE] = ABDOr [AOC – DOE] = ABCHence proved. | |

In the adjacent figure AB|| CD., CD|| EF and y:z esiquelto 3:7, find x |
| Answer» Given In the adjacent figure AB||CD; CD || EF and y:z =3:7, find x.y / z = 3 / 7\xa0y = 3 / 7 zCD is parallel to EFy + z = 180 (alternate interior angle)\xa03/7 z + z = 180\xa03z + 7z / 7 = 180\xa010 z = 1260 z = 126 degree\xa0So y = 3/7(126) y = 54 degreeAB is parallel to CDThere is a transversal in between. We know that sum of interior angles of same side of transversal is supplementary. So x + y = 180x + 54 = 180x = 180 - 54\xa0x = 126 degreeAB is also parallel to EF and x = z.Hence x = 126 degree | |

find the probability of getting 2 headswhen 2 coins are tossed |
|
Answer» 1/4 2 coins means 4 outcomes2 heads on 2 coins so the probability is 2/4 When two coins are tossed then its sample space is:-{HH , HT , TH , TT}Let us denote the event P(A) by the two heads when tossed.Total outcomes :- 4As we have to find the probability of 2 heads so there is only and only one faveourable outcome.Favourable Favourable outcome :- 1 {HH}Probability of event P(A) = Favourable outcomes _____________________ Total outcomesProbability of event P(A) = 1 _ 4So the probability of getting two heads when two coins are tossed is 1/4.HOPE IT HELPS YOU!REGARDS,SHUBHAM 1/4 |
