I should know this but dont. I need to find the height of a parallelogram with area given as 28 and base as 7. Help please? I also have to right the formula for it (e.g. h=????)

anonymous · Answer

remember area = long*short*sin(angle between them)
and
height = short*sin(angle between them)
|dw:1383114070191:dw|

anonymous · Answer

28 = 7*side*sin(a)
h = side*sin(a)
good so far?

anonymous · Answer

set this equation, 28 = 7*side*sin(a),  equal to side*sin(a)

anonymous · Answer

then substitute it into the height equation

anonymous · Answer

hint, your answer will be between 3 and 7 ^_^
