3x - 7 = 5x + 13
-3x = -3x
-7 = 2x + 13
-13 = -13
-20 = 2x
/2 = /2
-10= x

3 x - 7 = 5 x + 13

3 x - 5x = 13 + 7

-2x = 20

x = 20 / -2

x = - 10

If 1 angle is 55 and another is 55 add 20 (75) if you added them together it would be 130 so do 180 - 130 hope this helped!!

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: $\frac{1}{4}\sqrt{2}$
