The measure of the arc (S) given the angle it intercepted (A) and the radius is given by the equation,
                                     S = (A / 360°) x (2πr)
Substituting the values to the equation above,
                                       4 ft = (A / 360°) x (2π)(10 ft)
The value of A is 22.92°.

Answer:

22.92 degrees.

Step-by-step explanation:

We have been given that

s = 4 ft

r = 10 ft

We have to find the angle in degrees.

We know the relation

\theta=\frac{s}{r}

Here angle is in radians.

Substituting the values, we get

\theta=\frac{4}{10}\\\\\theta=\frac{2}{5}\text{ radians}\\\\\theta=0.4\text{ radians}

1 radian = 57.2958 degrees.

Hence, 0.4 radians = 22.92 degrees.

Therefore, the degree measure of the angle is 22.92 degrees.

Answer:

81.75 ft²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = \frac{1}{2} h (a + b)

where a, b are the parallel bases and h is the perpendicular height

Calculate h using the right triangle and the sine ratio

sin30° = \frac{opposite }{hypotenuse} = \frac{h}{10}

Multiply both sides by 10

10 × sin30° = h, thus

h = 5

a = 12 and b = 8.7 + 12 = 20.7, hence

A = \frac{1}{2} × 5 × (12 + 20.7)

   = 0.5 × 5 ×32.7

   = 81.75 ft²
