1) find the length of the longer diagonal of the rhombus with sides of 6cm and acute angles of 40 degrees When it states longer i havent a clue how

1) find the length of the longer diagonal of the rhombus with sides of 6cm and acute angles of 40 degrees

When it states longer i havent a clue how to write that our and or determine how to find length of the sides.

2) find the standard form of the equation of the eclipse with the vertices at (0,+-8) and the foci at (0,+-5)

I dont know how to answer this questionjQuery2240639987639970832_1531957665371 Or what standard form is specifically or whether their is an equation associated with this form? I know what the foci is but how to find the answer within this kind of question is still a mystery.

3) find the vertices, foci and the equations of the asymptotes for the hyperbola

Same kind of question. Dont know how to find foci and with it incorporated in this kind of question it throws me off with this kind of equation.

x^2/36 - y^2/25=1

Need help understanding these kinds of problems this is not anything i have to submit these are practice problems which already have answers to them however dont have any methods to break it down. (Why cant i just ask a GD question!!! I made sure i paid my dues and asked the questions which are necessary to ask which i have problems with). Wtf mane then when i ask for a refund y'all say " well it looks like you used up most of your questions on your account" Because y'all allowed me to submit work like this until my Tutor questions got low and strategically decided to f*** me over!..........Y'all some straight crooks! Cant even let tutors do their GD job
