In circle S,diameter PN is drawn .If measurement arc MN=110 degrees and PS=10 then find the length of MN to the nearest tenth.Sh

Goryan [66]

Answer:

$MN=16.4\ units$

Step-by-step explanation:

step 1

Find PN

we know that

PN is a diameter

PS is a radius

$PS=10\ units$

so

$PN=2*PS=2*10=20\ units$

step 2

Find the measure of arc MP

$arc\ MN+arc\ MP=180\°$

$arc\ MN=110\°$

$arc\ MP=180\°-110\°=70\°$

step 3

Find the measure of angle MNP

we know that

The inscribed angle measures half that of the arc comprising

substitute the value

step 4

Find the measure of angle MPN

we know that

The inscribed angle measures half that of the arc comprising

substitute the value

step 5

Find the measure of angle NMP

The sum of the internal angles of a triangle must be equal to 180 degrees

therefore

The triangle MNP is a right triangle

step 6

Find the length MN

In the right triangle MNP

$sin($

substitute the values

$sin(55\°)=\frac{MN}{20}$

$MN=(20)sin(55\°)=16.4\ units$

Bryce’s new t.v. is 3 1/3 feet long and 1 1/4 feet wide. What is the perimeter of the t.v.?

Alborosie

The perimeter of the TV is 9 1 / 6 ft

<h3>Perimeter:</h3>

Perimeter is the distance around a two-dimensional shape. The perimeter is the sum of the whole sides.

Therefore, the perimeter of the rectangular TV is as follows:

perimeter = 2(l + w)

where

l = length
w = width

Therefore,

l = 3 1 / 3 ft = 10 / 3 ft

w = 1 1 /4 ft = 5 / 4ft

perimeter = 2(10 / 3 + 5 / 4)

perimeter = 2( 40 + 15 / 12)

perimeter = 2(55 / 12)

perimeter = 55 / 6

perimeter = 9 1 /6 ft
