Find the area of the trapezoid

Mathematics
1 answer:
fiasKO [112]3 years ago
7 0

Answer:

C. 52\sqrt{3}\ ft^2

Step-by-step explanation:

Use formula for the area of trapezoid

A=\dfrac{a+b}{2}\cdot h,

where a is the smaller base, b is the larger base and h is the height.

From the diagram,

a=11\ ft\\ \\b=15\ ft\\ \\h=4\sqrt{3}\ ft

So, the area of trapezoid is

A=\dfrac{11+15}{2}\cdot 4\sqrt{3}=13\cdot 4\sqrt{3}=52\sqrt{3}\ ft^2

Can somebody help me with these problems please
mario62 [17]

Answer:

11. A. \frac{12}{13}

12. D. \frac{35}{12}

Step-by-step explanation:

11: Sin is just the side opposite of the angle divided by the hypotenuse of the triangle

Opposite of A = 36

Hypotenuse of the triangle = 39

36/39 = \frac{12}{13}

12. Tan is the side opposite of the angle divided by the side adjacent to the angle

Opposite of C = 35

Adjacent to C = 12

35/12 = \frac{35}{12}

Hope this helps!
