what does theta mean?

you do :). The area of any 4 parallel sided figure is base * height. (square, rectangle, parallelogram). height is not to be confused with side length; it is the total height o the parallelogram. simply take base times height. don't use alchemista's way, that is a more advanced math class

Area of a trapezoid: \[A = \frac{ b_1+ b_2}{ 2 } * h\] where b1 and b2 are the two differently sized bases and h is the height

which are the bases?

OpenStudy (anonymous):

you can also add the area of the two triangles + the area of the square. you'll get the same answer

the top base (8 cm) and the bottom base (2 + 8 + 2 cm)

how about this one.. its a little different. identify DEF -->HIG as a reflection, rotation or glide reflection. find the reflection line, translation rule, center and angle of rotation, or glide translation rule and reflection line. A. rotation; 180* about (-0.5,0) B. glide reflection;translate 8 units to the right then reflect across the line y=4. C. reflection; x=5 D. rotation; 180* about (1,4)

i assumed the base of the left triangle was 2 making the total 12 cm. it is 14 cm. the left triangle has a base of 4 and not a base of 2. the base of 4 can be confirmed using tan45 = 4/x --> x being the base were looking for, for its should be (8 + 14)*4/2 = 44

i think you should make a new thread for this translation/reflection thing. its been too long, i wouldn't be able to explain it properly. best of luck :) going afk 5 mins actuallly
