46+w=231
w=185
# brown eggs (46) + # white eggs (w) = total # of eggs (231)
Angle measurement DEF=107 degrees
You must first find angle F- since it is against a flat line, we know 180=F+135. Subtract 135 from each side and we find F is 45 degrees.
Then, since a triangle’s angles must always equal 180 degrees, we subtract angles D and F from 180 to get 107 degrees.
Answer:
whats the equation?
Step-by-step explanation:
Area of the figure=area of the square - area of the rectangle 1 - area of the rectangle 2.
Area of the square=side x side=12 * 12 =144
Area of the rectangle 1=8 *5=40
Area of the rectangle 2=5 * (12-8)= 5 * 4=20
Area of the figure=144 - 40 -20=84
Answer : 84
