Aparallelogram has sides of lengths 30 cm and 70 cm and one angle of measure 65 degrees. approximate the length of each diagonal to the nearest centimeter. use the law of cosines.

diagonal x= 63.5cm

diagonal y= 87cm

Step-by-step explanation:

Please see the attached file.

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
