sinA - cosA +1 / sinA + cosA -1 = secA + tanA
Now secA = 1/cosA and tanA = sinA/cosA
So sinA - cosA +1 / sinA + cosA -1 = 1/cosA + sinA / cosA
From now on I'll write sinA = s and cosA = c :-
(s - c + 1 )/ (s + c - 1) = 1/c + s/c
(s - c + 1) / (s + c - 1) = (1 + s) / c
Cross multiply:-
s + c - 1 + s^2 + sc - s = sc - c^2 + c
s^2 + c + sc - 1 = sc - c^2 + c
s^2 - 1 + sc - sc + c - c = -c^2
s^2 - 1 = -c^2
-(1 - s^2) = - c^2
Now 1 - s^2 = c^2 so:-
- c^2 = - c^2
So the identity is proved
There are 36 inches in one yard.
Since In total there is 25 attractions and shops , you would add them because there is still a chance that if it was randomly selected you would get a attraction. If 5/20 is the probability, you would divide 5 by 20 because the “ / “ sign means divide. And if it said 5 of 20 , it would mean multiply as “of” means multiply. So after you do the 5 divided by 20 , it equals 0.25, which comes out to a quarter of 100 which means it is 1/4 chance of getting a gift shop chosen. Answer : 1/4.

Answer:
C
Step-by-step explanation:
They can't form a triangle because the sum of 2 sidelengths is ALWAYS greater than the 3rd side in a triangle. Because 5+7=12<14, this means that it can't form a triangle.
