Answer:
this figure is Rhombus so 1 = 90
then 2= 60
Step-by-step explanation:
In every parallelogram, when you have two diagonal segment bisectors, you will always have a circumcentre showing all midpoints of both segment bisectors, plus, it measures 90° all around, so to get the m∠2, simply do this:
180° = 30° + 90° + m∠2
180° = 120° + m∠2
- 120° - 120°

B) 48cm²
find the area of the 2 rectangles
A = bh
A = 9×4
A = 36
A = 6×2
A = 12
add them up you get 48cm²
