Step-by-step explanation:
Answer:
Step-by-step explanation:
A. 3x+21=6x-60 -> 3x=81 -> x=27. So false. The value of x=27.
B. True. Alternate interior angles theorem.
C. False. The marked angles are alternate interior angles.
Answer:
C. 120 m²
Step-by-step explanation:
The surface area is equal to the area of 4 rectangles + area of 4 triangles + area of base.
Area of 4 rectangles:
4(5 × 4)
4(20) = 80
Area of 4 triangles:
4(3 × 4 × 1/2)
4(6) = 24
Area of base:
4² = 16
Add the areas.
16 + 24 + 80
= 120
The surface area of the composite solid is 120 m².
answer is equal to 82 coz x =9 and y=1
