Which equation could be used to find the value of x?
triangle def where angle e is a right angle. de measures x. df measures 55. angle d measures 49 degrees.
cos 49° = x over 55
cos 49° = 55 over x
sin 49° = x over 55
sin 49° = 55 over x

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
