Find the value of each variable. For the circle, the dot represents the center.

Musya8 [376]

Answer:

Part 1) The measure of angle d is 65°

Part 2) The measure of angle c is 89°

Part 3) The measure of arc a is 131°

Part 4) The measure of arc b is 47°

Step-by-step explanation:

we know that

In an inscribed quadrilateral, opposite angles are supplementary

step 1

Find the measure of angle d

∠d+115°=180°

∠d=180°-115°=65°

step 2

Find the measure of angle c

∠c+91°=180°

∠c=180°-91°=89°

step 3

Find the measure of arc a

we know that

The inscribed angle measures half that of the arc comprising

115°=(1/2)[99°+arc a]

230°=[99°+arc a]

arc a=230°-99°=131°

step 4

Find the measure of arc b

we know that

The inscribed angle measures half that of the arc comprising

∠c=(1/2)[arc a+arc b]

substitute the values

89°=(1/2)[131°+arc b]

178°=[131°+arc b]

arc b=178°-131°=47°

Simon has a certain length of fencing to enclose a rectangular area. The function A models the rectangle's area (in square meter

ss7ja [257]

Answer:

The maximum area is 1,600 square meters

Step-by-step explanation:

<u><em>The complete question is</em></u>

What is the maximum area possible?

The given function area is modeled by A(w)=-w(w-80)

we know that

The given function is a vertical parabola open downward

The vertex is a maximum

The x-coordinate of the vertex represent the width for the maximum area

The y-coordinate of the vertex represent the maximum area

Convert the quadratic function in vertex form

$A(w)=-w(w-80)\\\\A(w)=-w^{2}+80w$

Factor -1

$A(w)=-(w^{2}-80w)$

Complete the square

$A(w)=-(w^{2}-80w+1,600)+1,600$

Rewrite as perfect squares

$A(w)=-(w-40)^{2}+1,600$ ----> function in vertex form

The vertex is the point (40,1,600)

therefore

The maximum area is 1,600 square meters
