1 Find The Length Of The Longer Diagonal Of The Rhombus With Sides Of 6cm And Ac

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

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

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

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.
