What is the unknown fraction
Veseljchak [2.6K]

Answer: B. 8/100

      Let's give 5/10 a denominator of 100 since 58/100 does, so they have common denominators:

5/10 * 10 = 50/100

      Now, we can subtract 50/100 from 58/100 to find the unknown fraction:

58/100 - 50/100 = 8/100

      This gives us an answer of,

                   B. 8/100

100 POINTS!!! can someone please explain how to do this?
ivolga24 [154]

Answer:

x =pi/2,3pi/2

Step-by-step explanation:

sin²(x) - cos²(x) - sin²(x) = 0

Simplify

sin²(x)  - sin²(x) = 0

Leaving us with

- cos²(x)  = 0

Divide each side by -1

- cos²(x/-1  = 0/-1

 cos²(x)  = 0

Take the square root of each side

sqrt( cos²(x))  = sqrt(0)

 cos(x)  = 0

Taking the inverse cos of each side

cos^-1(cos(x))  = cos^-1(0)

x = pi/2     x = 3pi/2
