A is 18 degrees
B is 81 degrees
C is 81 degrees

I solved this problem by finding x, then plugging it into each little equation. B and C are the same because is is an isosceles triangle. You can tell this from the beginning because their equations are the same. Hope this helps :)

If r = -\sqrt{2}, and a5 = \sqrt{2}, what is the first term of the sequence?
shepuryov [24]

Answer: C

<u>Step-by-step explanation:</u>

Let x represent the first term (a₁)

a₁ = x

a₂ = x(-√2)  = -x√2

a₃ = -x√2(-√2)  = 2x

a₄ = 2x(-√2)   = -2x√2

a₅ = -2x√2(-√2)   = 4x

Since it is given the a₅ = √2, then we  can solve: 4x =√2

Divide both sides by 4 to get: x = \frac{\sqrt{2}}{4}

this can also be written as: \frac{1}{4}\sqrt{2}
