Find the measure of MNQ

Mathematics
1 answer:
xz_007 [3.2K]3 years ago
8 0

Answer:

m∠MNQ = 158

Step-by-step explanation:

As it can be seen in the figure:

+) The measure of arc MQ = 91 degree

+) The measure of arc RP = 225 degree

As this is the circle, four points M, Q, P and R are on the circle, so that we have:

+) m∠RMP = 1/2. measure of arc RP = 1/2 x 225 = 112.5 degree

As N is on MP

=> m∠RMN = m∠RMP = 112.5

+) m∠ MRQ = 1/2 measure of arc MQ = 1/2 x 91 = 45.5 degree

As N is on RQ

=> m∠MRN = m∠MRQ = 45.5

In the triangle RMN, the total measure of 3 internal angles is equal to 180 degree, so that:

m∠MNR + m∠RMN + m∠MRN = 180

=> m∠MNR + 112.5 + 45.5 = 180

=> m∠MNR  = 180 -112.5 -45.5 = 22

As N is on QR

=> m∠MNR + m∠MNQ = 180

=> m∠MNQ = 180 - m∠MNR  = 180 - 22 = 158

So that m∠MNQ = 158

PLEASE PLEASE HELP!! Sketch a triangle and label correctly. Work must be shown for this problem. Round answers to the nearest hu
torisob [31]

Answer:

Please see attached image for the sketch with the labels.

Length "x" of the ramp = 11.70 ft

Step-by-step explanation:

Notice that the geometry to represent the ramp is a right angle triangle, for which we know one of its acute angles (20^o), and the size of the side opposite to it (4 ft). Our unknown is the hypotenuse "x" of this right angle triangle, which is the actual ramp length we need to find.

For this, we use the the "sin" function of an angle in the triangle, which is defined as the quotient between the side opposite to the angle, divided by the hypotenuse, and then solve for the unknown "x" in the equation:

sin(20^o)=\frac{opposite}{hypotenuse}\\ sin(20^o)=\frac{4}{x} \\x=\frac{4}{sin(20^o)} \\x=11.695\,\,ft

Therefore the length of the ramp rounded to the nearest hundredth as requested is: 11.70 ft

What is 5/11 minus negative 4/11
MA_775_DIABLO [31]

<u><em>Answer:  1/11 and 0.09=0.10</em></u>

Step-by-step explanation:

subtract by the numbers. subtract it's to take away one number from to another from the difference between the numbers.

5-4/11

5-4=1

=1/11

You can also round up to the nearest hundredths is 0.10.

Hope this helps!

Thanks!

Have a great day!

Luna's dining room is 19 feet wide and 22 feet long. Luna wants to install wooden trim
Marrrta [24]

9514 1404 393

Answer:

  $4.92

Step-by-step explanation:

The cost is found by multiplying the number of feet by the cost per foot. The number of feet is the perimeter of the dining room, the sum of the lengths of all the sides.

There are two sides of the rectangular room that are 19 feet, and two sides that are 22 feet, so the total length of trim is ...

  P = 2(L +W) = 2(22 ft + 19 ft) = 2(41 ft) = 82 ft

The cost is then ...

  cost = ($0.06/ft)(82 ft) = $4.92

It will cost Luna $4.92 to buy enough trim.
