If YV = 28 in, find the length of the major arc VYX. Round to the nearest tenth ( one decimal place).

denpristay [2]

Answer:

$VYX=84.3in$

Step-by-step explanation:

Given

$YV = 28in$

$\angle WZX = 15^\circ$

See attachment

Required

Determine the length of $VYX$

First, calculate the major angle VZX

$\theta = \angle VZX = 360 - \angle WZX$

$\theta = \angle VZX = 360 - 15$

$\theta = \angle VZX = 345$

$\theta = 345$

The length of arc VYX, is:

$L=\frac{\theta}{360} * 2\pi r$

Where

$r = \frac{1}{2} * Diameter$

$r = \frac{1}{2} * YV$

$r = \frac{1}{2} * 28$

$r = 14$

So:

$L=\frac{\theta}{360} * 2\pi r$

$L=\frac{345}{360} * 2 * \frac{22}{7} *14$

$L=\frac{345}{360} * 2 * 22 *2$

$L=\frac{345* 2 * 22 *2}{360}$

$L=\frac{30360}{360}$

$L=84.3in$

Hence, the length of VYX is:

$VYX=84.3in$

The shortest leg of a 30º-60º-90º triangle has a length of 6. Find the length of the other leg and the hypotenuse. Write your an

Natasha2012 [34]

Answer:

$leg=6\sqrt{3} \\\\hypotenuse=12$

Step-by-step explanation:

The equations for the 30°-60°-90° are as follows:

$l=\sqrt{3}*s$

$h=2*s$

l is the longer leg, s is the smaller leg, and h is the hypotenuse. Insert the known values and solve for the longer leg and the hypotenuse:

$l=6\sqrt{3} \\h=12$

Evaluate the expression when c= -5.<br> c^2+ 6c-9

sesenic [268]

Answer:

Explanation:

c² + 6c - 9

Insert -5 For 'c'

-5² + 6(-5) - 9

Follow P.E.M.D.A.S.

5² = 25

= -25 + 6(-5) - 9

Multiply: 6(-5) = -30

= -25 - 30 - 9

Simplify

KIM [24]

<em>A</em><em>nswer</em> : 6 keychains

Step-by-step explanation:

there are 12 inches in 1 feet

so,there 36 inches of string

Mia needs 6 inches for each keychain.

36/6 is 6.

so in total there's 6 keychains being made
