The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
Ummm 48 cm ima be honest I need some points my fault
Answer:
224 cubic meters
Step-by-step explanation:
3*4=12 (for both triangles)
4*9= 36 36*5=180 (for the 5 rectangles)
4*4=16 16*2=32 (for both squares)
12+180+32=224
