In a triangle ABC if r=3,R=6,r_(1)=9 then A=

In triangle ABC , AB=AC and AL is perpendicular to BC at L. In triangle DEF , DE=DF and DM is perpendicular to EF at M. If (area of triangle ABC ):(area of triangle DEF )= 9:25 then (DM+AL)/(DM- AL) is equal to: त्रिभुज ABC में, AB = AC है तथा AL, BC पर L पर डाला गया लम्ब है| triangle DEF में, DE = DF है तथा DM, EF पर M पर डाला गया लम्ब है| यदि ( triangle ABC का क्षेत्रफल ): ( triangle DEF का क्षेत्रफल )= 9 : 25 है, तो (DM+AL)/(DM- AL) का मान किसके बराबर है ?

The three perpendicular distances of three sides of an equilateral triangle from a point which lies inside that triangle are 6 cm, 9 cm and 12 cm respectively. The perimeter of the triangle is :- किसी समबाहु त्रिभुज के तीनो भुजाओं से समबाहु त्रिभुज के अन्दर एक बिंदु से लंबवत दूरी क्रमशः 6 सेमी 9 सेमी और 12 सेमी है, तो त्रिभुज का परिमाप ज्ञात करें-

If in a triangle angles are in the ratio 1:1:2 and the length of its longest side is 6 sqrt 2 cm, then what is the area (in cm^2 ) of the triangle? यदि किसी त्रिभुज में, कोण 1 : 1 : 2 के अनुपात में हैं तथा इसकी सबसे लंबी भुजा 6 sqrt 2 सेमी की है, तो इस त्रिभुज का क्षेत्रफल ज्ञात करें |

study the following information carefully and answer the questions given below it. An exhibition is open for pubic since 9 am till 3 pm and again since 4 pm till 10 pm in a day. There are 12 batches of 1 hour each. The entry ticket bears a pass code made up of seven words, which changes every hour following a particular rule. The pass codes for 4 pm to 10 pm are same as those for respective hours during 9 am to 3 pm i.e., the pass code for 4 pm to 5 pm is same as that of 9 am to 10 am and so on. Following is an illustration of the code and steps of rearrangement for subsequent clock hours. First batch : 9 am to 10 am (4 pm to 5 pm) Pass code : dig more and you will find water Second batch : 10 am to 11 am (5 pm to 6 pm) Pass code : and dig find you water will more Third batch : 11 am to 12 noon (6 pm to 7 pm) Pass code : find and will you more water dig and so on. If the pass code for 5 pm to 6 pm is 'out in above over the field end', what will be the pass code for 1 pm to 2 pm ?
