Find the measure of the central angle with a radius of 13 inches and the area of a sector measuring 42.25π square inches.
quester [9]
Area of a sector: 1/2r^2 theta

Need theta
Let x be theta for now

42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians

Radians => degrees is 1.57 * 180/pi or roughly 90.

A parking lot with an area of 9600 ft? (see diagram below) has a 200 ft fence built along
VLD [36.1K]

Answer:

x+y=200

xy=9,600

Step-by-step explanation:

The diagram shows rectangular parking lot with sides of x feet and y feet.

1. The area of the rectangle is  given by

A=Length \times Width

A = xy -------------------------(1)

We are given that the area of the parking lot is 9,600\ ft^2, then

eq(1) becomes

9,600  = xy ---------------------(2)

2. A parking lot has  a 200ft fence built along two adjacent sides of lengths x and y, then

Then the perimeter of the two adjacent sides

x+y=200 ---------------------------------(3)

Thus ,The system of two equations are

x+y=200

xy=9,600

Please help please i need help​

Answer:

d + 85

Step-by-step explanation:

Look at it like this,

suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS

or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.

notice that you always take the number of DVDs you already have, and add 85 to it.

d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards

<u>Question</u>

In the diagram, angle OLM is twice as large as angle PON. What is the size of angle OLM?

Answer:

\angle OLM =112^\circ

Step-by-step explanation:

Let Angle PON =x

Therefore: Angle OLM =2x

\angle JKO +\angle OKL =180^\circ\\124^\circ + \angle OKL =180^\circ\\\angle OKL =180^\circ-124^\circ\\\angle OKL =56^\circ

\angle PON =\angle KOL =x $ (Vertical Angles)

\angle OKL +\angle KOL=\angle OLM $(Opposite Interior Angles of Triangle KOL)

56+x=2x\\2x-x=56\\x=56^\circ

Therefore:

\angle OLM =2x=2*56=112^\circ
