Answer:

x = ±2sqrt(2)

Step-by-step explanation:

x^2 = 8

Take the square root of each side

sqrt(x^2) = ±sqrt(8)

x = ±sqrt(4*2)

We know that sqrt(ab) = sqrt(a)sqrt(b)

x = ±sqrt(4)sqrt(2)

x = ±2sqrt(2)

german

Answer:

x = 1

y = 30°

Step-by-step explanation:

is RS is ⊥ to TU then TS = US so we can use this equation to find 'x':

20x-3 = 5x+12

15x = 15

x = 1

we also know that RS intersecting with TU creates a 90° angle

if 3y = 90 then y = 30
