Which equation can be used to find the length of the missing side x? (The triangle displayed is pink and is a right triangle; x is on the straight angle, 7 is on the curved angle and 65 degrees is on where the triangle rests)

Note: *=degrees

A. x= 7cos65*
B. x=7sin65*
C. x=7/sin65*
D. x=7/cos65*

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.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

hope this !

c ) y = 2.5 x - 26.25
