Answer:

-104/41

Step-by-step explanation:

f(8) = -13

g(8) = 41/8

f/g(8) = -13/1 / 41/8 = -(13×8) / (41×1) = -104 / 41

f/g(x) = (3-2x) / (1/x + 5) = (3-2x)/1 / ((1+5x)/x) =

= x×(3-2x) / (1+5x) = (3x - 2x²) / (1 + 5x)

for x=8 this gives the same result.

Please help me with this geometry problem, I'd really appreciate it :)
Strike441 [17]

Hello from MrBillDoesMath!

Answer:

x = 31


Discussion:

angle A + angle C + angle B = 180              (180 degrees in a triangle)

angle A + 57           +  61        = 180 =>         (substitution)

angle A + 118 = 180 =>

angle A = 180 -118 = 62


By the congruence statement, angle A = angle D = 2x so

62 = 2x =>

x = 31



Thank you,

MrB
