Question

i) (5x-3)/(5x+2)x (x+2)/(x+6)
ii) (x²+1)/(x-1 )x (x+1)/(x²-x+1)
iii) (x³+1)/(x-1) x (x-1)/(2x)
iv) (x²-7x+12)/(x²-2x-3)x (x²-2x-24)/(x²-16)
Find the product and express the result in lowest form :-
*correct ans for the below questions are
i) (5x²+7x-6)/(5x²+32x+12)
ii) (x³+x²+x+1)/(x³-2x²+2x-1)
iii) (x³+1)/(2x)
iv) (x-6)/(x+1)
THOSE WHO GONNA ANS IT CORRECT WILL 15 THANKS IN JUST A SECOND
A GREAT DEAL HURRY UP!!!!​

Answer 1

Answer:

A + B = 90° => A = 90 - B

So Tan A = Cot (90 - A) = Cot B

So Tan B = Cot (90 - B) = Cot A

SecB = Cosec (90 -B) = Cosec A

CosA = Sin (90 -A) = Sin B

substitute these in the LHS,

Answer 2

Answer

Answer:

A + B = 90° => A = 90 - B

So Tan A = Cot (90 - A) = Cot B

So Tan B = Cot (90 - B) = Cot A

SecB = Cosec (90 -B) = Cosec A

CosA = Sin (90 -A) = Sin B
