Find the value of Sin(45-alpha) - cos (45+alpha)Need the answer as soon as possible |
|
Answer» sin(45-X) - cos(45+x) We know, Sin(theta) = cos(90°-theta) So, sin(45-x) -cos(45+x) =>cos(90-(45-x) -cos(45+x) =>cos(90-45+x) - cos(45+x) =>cos(45+x)-cos(45+x) =>0 {I have taken x in PLACE of ALPHA} So, sin(45-alpha)-cos(45+alpha)= 0 Cheers! |

What is the remainder when 77,777... up to 56 digits is divided by 19? |
|
Answer» Answer: Let, N= 77…(37times) Note: If a NATURAL number X = 19M + n where m,n BELONGS to natural numbers then X mod 19 = n mod 19 WKT N= 7(10^37–1)/9 => 9N=7(10^37–1) now, N mod 19= (9N mod 171)/9 [ 9 divides 9N] we have, 9N = 7[10{(1026–26)^12}-1] therefore 9N mod 171= 7[10{26^12}-1] mod 171 [ removing terms which are divisible by 171 in the binomial expansion of (1026–26)^12] => 26^12=(684–8)^6 =>9N mod 171 = 7[10{8^6}-1] mod 171 => 8^6=(513–1)^2 => 9N mod 171 = 7[10{1}-1] mod 171 =63 therefore, N mod 19 = 63/9 = 7 Hence the answer is 7

N a rhombus abcd, measure of angle cab is 25 , what is the measure of angle abc? |
|
Answer» Step-by-step explanation: In a rhombus ABCD measure of ANGLE cab is 25 then measure of angle abc ∠CAB = 25° in Δ ABC AB = BC ( all sides of a rhombus are EQUAL) AC is Diagonal as AB = BC => ∠CAB = ∠ACB => ∠ACB = 25° in Δ ABC ∠CAB + ∠ABC + ∠ACB = 180° => 25° + ∠ABC + 25 = 180° => ∠ABC = 130° |
