Answer:

Step-by-step explanation:

Angle A:

Because quadrilateral ABCD is cyclic, angles A and C are supplementary. This means angle A = 180 - 101 = 79 degrees

Angle B: same kind of logic as A

Solve s=2(lw+lh+wh) for w

Scilla [17]

   s = 2(lw + lh + wh)

Divide each side by 2 :    s/2 = lw + lh + wh

Subtract 'lh' from each side:       s/2 - lh = lw + wh

Combine the 'w' terms:      s/2 - lh = w(l + h)

Divide each side by (l + h): (s/2 - lh) / (l + h) = w

Find the surface area and show work

Law Incorporation [45]

Answer: $1,270in^2$

Step-by-step explanation:

The surface area of a rectangle can be calculated with:

$Area_{rectangle}=lenght*width$

The surface area of a trapezoid can be calculated with:

$Area_{trapezoid}=\frac{height}{2}(Larger\ base+Smaller\ base)$

Calculate the area of the base, wich is a rectangle:

$A_{1}=(34in)(15in)=510in^2$

There are two equal rectangles, therefore, multiply the area of any of them by 2:

$A_{2}=2(15in)(13in)=390in^2$

Calculate the area of the other rectangle:

$A_{3}=(15in)(10in)=150in^2$

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

$A_4=\frac{2(5in)}{2}(34in+10in)=220in^2$

Therefore, the surface area will be the sum of all the areas calculated:

$SA=A_1+A_2+A_3+A_4\\\\SA=510in^2+390in^2+150in^2+220in^2\\\\SA=1,270in^2$
