Which statement is true?
REY [17]

Choice (B) is true.

For (A): 5 is not a divisor of 14, whose only divisors are 1, 2, 7, and 14.

For (B): the factors of 10 are: 1, 2, 5, and 10. The factors of 15 are: 1, 3, 5, and 15. As we can see, the only, and greatest, common factor is 5.

For (C): 3 is not a factor of 13, which is a prime number.

For (D): again, 3 is not a factor of 14.

Find cos x if sin^2x-1/cos x = -1 a. –1 b. 2 c. 1 d. 0
irina1246 [14]

Answer:        1

Step-by-step explanation:

Alright, lets get started.

The given expression is :

\frac{sin^2x-1}{cosx}=-1

As per Pythagorean identity,

sin^2x + cos^2 x = 1

taking 1 to left side and cos^2 x to right side

sin^2 x-1=-cos^2x

Now plugging the value of sin^2 x-1 in given expression

\frac{-cos^2x}{cosx} =-1

cosx will be cancelled, so

-cosx=-1

Multiplying -1 in both sides, it will equal to

cos x= 1    ........................ Answer (C)

Hope it will help :)
