Solve the following pair of linear equations by the substitution method :-S-t=3S/3+t/2=6 |
|
Answer» s-t=3....1s/3 +s/2=6......2from eq 1 we get, s=3+tPutting this value of s in eq 2 .3+t/3 + t/2 = 6 6+2t+3t/6=66+5t=6×6 6+5t=36 5t =36-65t=30 t=6 now ,substituting this value of t in eq1 s-6=3 s=3 + 6s=9 Ok brthr so do.. I can do it S-t=3.......1S/3+1/2=6............2Using equation (1) we can say that S=3+tPutting in equation (2)We get3+t/3+t/2=66+2t+3t/6=65t+6=365t=30t=6Putting the value of t in equation 1We get S-6=3S=3+6S=9 Mere bhaiyo or unki bhno koi h kya kr do plz ?hey can anyone solve this ques... |

The angles of a triangle are in AP the greatest angle is twice the least find the all angles |
| Answer» Let the three angles of triangle which are in A.P. be a - d, a, a + dNow, sum of the angles = 180°{tex}\\Rightarrow{/tex}\xa0a - d + a+ a + d =\xa0180°{tex}\\Rightarrow{/tex}\xa03a = 180°{tex}\\Rightarrow{/tex}\xa0a = 60°It is given that,a + d= 2(a - d){tex}\\Rightarrow{/tex}\xa0a + d = 2a - 2d{tex}\\Rightarrow{/tex}\xa0a = 3d{tex}\\Rightarrow{/tex}\xa060° = 3d{tex}\\Rightarrow{/tex}\xa0d =\xa020°Thus, the angles of triangle are 40°, 60°, 80°. | |

The angle of a quadrilateral are in AP whose common difference is 10 find the angles |
| Answer» Let the required angles be (a - 3d)°, (a - d)\xa0°, (a + d)\xa0°\xa0and (a + 3d)\xa0°Common difference = (a - d) - (a- 3d) = a - d - a + 3d = 2d\xa0We are given that Common difference = 10°{tex}\\therefore{/tex}2d = 10°\xa0= d = 5°We know that sum of four angles of quadrilateral = 360°{tex}\\Rightarrow{/tex} (a-3d)o +(a-d)o+(a+d)o+(a+3d)o=360o4a=360oa={tex}\\frac{{360}}{4}{/tex}=90o{tex}\\therefore{/tex}a=90o and d=5oFirst angle = (a - 3d)°\xa0= (90 - 3\xa0×\xa05)\xa0°\xa0= 75°Second angle = (a - d)° = (90 - 5)\xa0°\xa0= 85°Third angle = (a + d)° = (90 + 5°) = 95°Fourth angle = (a + 3d)° = (90 + 3\xa0×\xa05)° = 105° | |
