The longer diagonal of a rhombus measures 20 cm. the rhombus has an angle that measures 100 degrees. determine the perimeter of the rhombus, to the nearest tenth.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

believe it or not anna is correct good job anna give me a fist bump there u go gal
