9^2 = 2x^2
81 = 2x^2
40.5 = x^2
6.36 = x
I think the side length of the square would be around 6.36 cm.

Find the measurements of the numbered angles in each isosceles trapezoid.
SSSSS [86.1K]

Answer:

∠1 = 96°

∠2 = 84°

∠3 = 84°

Step-by-step explanation:

∠1 = 96°

∠2 = ∠3

∠1 + 96 + ∠2 + ∠3 = 360°

∠2 = (360 - 96 - 96)/2 = 84°

∠3 = 84°

x^{2} +16 \\  \\ 
= x^{2} +(4)^{2} \\  \\ 
= x^{2} -(-1)(4)^{2}   \\  \\ 
= x^{2} -i^{2} (4)^{2} \\  \\ 
= x^{2} -(4i)^{2} \\  \\ 
=(x+4i)(x-4i)

Solve (x + 5)2 = 48.
natita [175]

Answer:

x = -5  ±4sqrt(3)

Step-by-step explanation:

(x + 5)^2 = 48

Take the square root of each side

sqrt((x + 5)^2) = ±sqrt(48)

x+5 = ±sqrt(16*3)

x+5 = ±4sqrt(3)

Subtract 5 from each side

x = -5  ±4sqrt(3)
