Given the width of the lawnmower is 5 feet and the
length of the rope is 20 feet, calculate the radius (R) of
the pole that will produce a perfect lawn.

R=

Answers

Answer 1

Answer:

  R=0.39789 ft

Step-by-step explanation:

For the perfectly mowed lawn, after one revolution, you want the lawnmower to be exactly one lawnmower's width closer to the pole. This implies that one lawnmower width should wrap around the circumference of the pole every revolution. So for this lawnmower we want:

2πR=2.5

⇒R=2.5/2π

  R=0.39789 ft

2. One angle of a triangle measures 10 degrees more than the second. The measure of the third angle is twice the sum of the measures of the first two angles. Find the measure of each angle. [Hint: the sum of the three angles in a triangle equals 180°.] PLEASE SHOW YOUR WORK I WILL MAKE BRAINLIST PLEASE!!!!!!!

Answers

Answer:

first angle = 25 degrees

Second angle = 35 degrees

Third side = 120/degrees

Step-by-step explanation:

Let the size of the second angle be x degrees.

One angle of a triangle measures 10 degrees more than the second. This means that the size of the first angle is ( x+ 10 )degrees.

The measure of the third angle is   twice the sum of the measures of the first two angles. This means that   The third angle = 2( first angle + second angle). So the size of each angle is  

First angle (x + 10) degrees  

Second angle = x degrees

Third angle = 2(x + 10 + x) =  (4x + 20) degrees

Sum of angles in a triangle = 180  degrees. Therefore,  x + 10 + x + 4x + 20 = 180 degrees  6x + 30 = 180

6x = 180 - 30 = 150

x = 150/6 = 25 degrees

First angle = x + 10 = 25 +10 = 35

Third angle = 4x + 20 = 4 × 25 + 20

= 100+ 20 = 120 degrees

Hope this helps

Answer:25(1st angle),35(2nd angle),120(3rd angle)

Step-by-step explanation: (/ stands for divide)

180/6=30 (sum of angles/total units=value of one unit, third angle is 4 units as it is twice the sum of first two angles)

30x4=120 (value of unitxnumber of units of 3rd angle=3rd angle)

30x2=60 (value of unitxfirst angle+second angle total units=value of 1st angle+2nd angle)

(60-10)/2=25(1st angle)

25+10=35(2nd angle)

CHECK: 35+25+120=180

hope you get it :)

Mrs. Casiple is making a table cloth for her circular dining table 10 dm in radius. She wants the cloth to be hanging around the edge of the table by 4 dm. How big will the table cloth be? Use π=22/7

Answers

The area of the dining tablecloth would be 616 dm² which is a circular dining table 10 dm in radius.

What is the area of the circle?

The area of the circle is equal to the product of the square of the radius of the circle and pi.

A = πr²

where 'r' is the radius of the circle

Mrs. Casiple is making a tablecloth for her circular dining table 10 dm in radius. She wants the cloth to be hanging around the edge of the table by 4 dm which is given in the question.

Here the radius of the dining table = 10 dm.

The extra length = 4 dm

Total radius = 10 dm + 4 dm = 14 dm

Area of dining table cloth = πr²

Area of dining table cloth = 22/7 × (14)²

Area of dining table cloth = 616 dm²

Therefore, the area of the dining tablecloth would be 616 dm²
