A central angle measuring 120° intercepts an arc in a circle whose radius is 3.

Answer:

6.28

Step-by-step explanation:

The length of arc which subtends an angle \alpha at the center of a circle is given by \alpha r where r is the radius of circle.

______________________________

given

the central angle of arc is  120°

\pi = 180\\120 = (\pi /180)* 120\\120 = 2/3\pi

we will use value of \pi as 3.14

r = 3

Length of this arc is

2/3( \pi *3) = 2\pi \\=2*3.14 = 6.28

The length of the arc to the nearest hundredth of unit is 6.28

You need to estimate the square root of 200 ft². Rewrite 200 as 2 x 100, then square root of (2*100) is:

10*sqrt(2). The sqrt(2) = 1.414, so the length of each side of the square will be 10*1.414 = 14.14 ft or about 14 ft.

Help me i have been trying to solve it. plzz
siniylev [52]
Because completementary angles add up to 180 degrees (angle 3 and angle 4)
and interior angles of a triangle will also add up to 180 degrees

if you compare these two facts, then angle 4 equals the 2 non adjacent interior angles

Answer:

y=60° b=60°

Step-by-step explanation:

the sum of all degrees of interior triangle is 180

in the first one, 30° and 90° have been given.(that small square represent 90°)

so 180°-90°-30°=60°

in the second one, the 120° is on the other side of a line, a line has a degree of 180, therefore the interior angle is 60°, the same rule 180°-2*60°=60°
