An arc on a circle measures 85°. The measure of the central angle, in radians, is within which range? 0 to StartFraction pi Over

barxatty [35]

Answer:

0 to StartFraction pi Over 2

Step-by-step explanation:

we know that

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

The central angle in degrees is within the range $(0,90^o)$

Convert to radians

Remember that

$\frac{\pi}{2}\ radians=90^o$

therefore

the range in radians is $(0,\frac{\pi}{2})$

0 to StartFraction pi Over 2

(4 X 10^4)

= 73 + 24000000

40000

= 24000073

a flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 19 feet mor

Neporo4naja [7]

Let's assume

shorter side as x

so, first side =2x

third side =x+19

now, we can find perimeter of triangle

perimeter of any triangle is

first side + shortest side + third side

so, we get

$P=2x+x+x+19$

we are given perimeter=187

so, we can set it to 187

and then solve for x

$187=2x+x+x+19$

$187=4x+19$

$4x+19-19=187-19$

$4x=168$

$x=42$

so,

shortest length is x=42 feet

First side =2x=2*42=84feet

third side =x+19=42+19=61 feet

so, dimensions are

first side is 42 feet

second side is 84 feet

third side is 61 feet................Answer
