Answer:

Step-by-step explanation:
We have:
(1) two trapezoids with bases b₁ = 7cm and b₂ = 5cm and the height h = 4cm
(2) three rectangles 3 cm × 7 cm, 3 cm × 4 cm and 3 cm × 5 cm.
The formula of an area of a trapezoid:

Substitute:

Calculate the areas of the rectangles:

The Surface Area:

19+ 17 = 36
right angle = 90°
90 - 36 = 54

The answer to what is the measure of ∠acb is 34.7
Answer:
each taco costs $3
t = (23-2)➗(4+7)
Step-by-step explanation:
t represents the cost of one taco
23 is the total cost and 2 is the cost of the salse, the 3 is how many tacos you got and the 4 is how many your friend got.
t = (23-2)➗(3+4) First solve what‘s in the brackets
t = 21 ➗ 7 Then divide whats left
t = 3 That gives you answer of 3 per taco
