Required area of shaded portion
= Area of square ABCD - 4 × area of one quadrant

Answer:
I'm about 3 months haha, but I'll still help you out. Angle E is equal to 75 degrees.
Step-by-step explanation:
multiply 3.5 x 3 = 10.5
add -5 +-10 = -15
so you have 10.5 x 10^15
then you need to move the decimal point 1 place to the left to get 1.05
since you move the decimal point 1 place to the left you add 1 to the -15 to get -14
so answer = 1.05 x 10^-14
