  A: not in standard form (coefficients are not integers)

  B: 2/-5 = -2/5 . . . not -1/2

  C: 1/-2 = -1/2 . . . a good candidate

  D: 1/-1 = -1 . . . not -1/2

Can someone help me with number 6?
serg [7]

Answer:

The answer to your question is:

a) sinФ = -4/√17

b) cosФ= 1/√17

c) tanФ = -4

Step-by-step explanation:

Just draw a right triangle where the opposite leg is -4/√17 the adjacent leg is 1/√17 and the hypotenuse is 1.

then sine Ф = opposite / hypotenuse   = -4/√17 / 1 = -4/√17

      cosine Ф = adjacent /hypotenuse = 1/√17 / 1 = 1/√17

      tan Ф = opposite / adjacent  = -4/√17 /  1/√17 = -4/1

will give brainliest!!!!! will give brainliest!!!!! will give brainliest!!!!! will give brainliest!!!!! will give brainliest!!!!
Marrrta [24]

Answer:

849.24 cm²

Step-by-step explanation:

we know it is a cube so to find the surface area of each square you do

12x12=144 and there are 5 sides so 144x5=720

We know sides of the squares are 12 cm so half of that (6) would be the bottom of the triangle

Now using pythagorus you would do a²+b²=c²

15²+6²=c²

225+36=c²

√261=√c²

16.15=c       this only half of one of the sides of the pyramid so you would times 16.15 by 8 to equal 129.24

now add 720+129.24=849.24 cm²
