    Could you tell the value of angle ABD from the figure?

    I know that ABD is 90 degrees of the right angle symbol

    okay, from the figure we know that angle ABD= 3x = 90 Can you find value of x?

    Do I just divide 90/3? Sorry for all the stupid questions

    ok, let me explain we have 3x= 90 divide both sides by 3 3x/3= 90/3 or x= 90/3 Do you follow? No question is stupid :)

    good, also from figure angle DBC= 2x+3y =90 so we have 2x+3y=90 Can you solve for y? you already know the value of x?
