When a object see up to down is called angle of depression and when a object see down to up is called angle of elevation. Hopefully you understood what I said Nhi Rahul U gone Depression upper or elevation niche.... Watch vidio for it as per my opinoion |

If sin 3A =cos (A-26°) ,where 3Ais an acute angle ,find the value of A |
|
Answer» If we change the sin to cos so we do 90 -3A =cos A- 26 cos se cos cancel 90-3a= a-26 4a = 116 a= 26 Sol= Given that Sin 3A = cos (A-26°) We know that SinA= cos(90-A) SO, Cos( 90-3A)=cos(A-26°) 90+26= A+3A 116=4A A=116÷4 A=29. Ans This question is given in NCERT also. Example 10 and Pg no. 189. A=29 my answer A= Sin3A=cos(90-3A). Then putting the value. Cos and Cos get cancelled then. 90-3A=A-26. Then 90+26=A+3A. 116=4A. A=116/4. A=29. -- answer |

Find the sum of first fifty natural numbers |
|
Answer» (1) 1+2+3+4+………………+48+49+50.If we start adding the first & the last numbers1+50= 512+49 = 513+ 48 = 514+ 47 = 51………..This way if we continue.. Towards the end we get…24 + 27 = 5125 + 26 = 51That shows, by adding them we get 51, 25 times.So the total will be 51 * 25 = 1275 . (2) So we can frame a formula now, whenever , the sum of first ’n’ numbers are to be found out…SUM = n/2 * (n+1) = 50/2*(50+1) = 25*51= 1275[3] or, The sum of any ‘n’ numbers = Sn =n/2 { 2a + (n-1)d} = 50/2 {(2+ 49*1}= 25*51= 1275 1275✌✌?? Emoji nhii Diya? Sorry bro my multiplication is wrong,emoji is correct and rest all r correct 25×51=1275? ... Ap:1,2,3.........Here a=1,d=1,n=50Sn=n/2[2a+(n-1)d]=50/2[2+(50-1)1]=25[2+49]=25(51)=2499 |
