Answer:
suggestions use algebra calculator or mathaway
12) Angle ACD= Angle ABC+ Angle CAB ====> You MAY end here
That is, Angle ACD= 132+21
Angle ACD= 153
13) Angle ABC+ Angle BAC= Angle ACD====> You MAY end here
That is, Angle ABC +16=143
-16= -16
Angle ABC=127
Yes! You do flip the sign if you are dividing by a negative.
So,
-6x>54
x<-9

Answer:
256 cm^2
Step-by-step explanation:
The area of the rectangle is the product of its length and width.
A = (16 cm)(10 cm) = 160 cm^2
The area of each triangle is half the product of its base and height.
A = (1/2)(16 cm)(6 cm) = 48 cm^2
__
Then the area of the rectangle and 2 triangles is ...
160 cm^2 + 2(48 cm^2) = 256 cm^2
The area of the composite figure is 256 cm^2.
