Find the value of x.
picture below \/

x = 139

Step-by-step explanation:

This figure is a quadrilateral.  The angles add up to 360 degrees

47+82+92+x = 360

Combine like terms

221+x =360

Subtract 221 from each side

221+x-221 = 360-221

x = 139

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
