Answer:

Angle B=92

Arc DCB=228

Step-by-step explanation:

Arc DCB intercepts Angle A.

Arc DCB is twice of Angle A so that means Arc dCB=228

Angle C is supplementary so Angle B equal 92.

Which of the following is true of the location of an angle, Theta, whose tangent value is Negative StartFraction StartRoot 3 End

Anuta_ua [19.1K]

The value of theta has a 30-degree reference angle and is located in Quadrant II or IV.

Given to us

$tan \theta =-\dfrac{\sqrt{3}}{3}$

<h3>What is the value of $tan \theta =\dfrac{\sqrt{3}}{3}$ ?</h3>

To know the value $tan \theta =\dfrac{\sqrt{3}}{3}$ we will simplify the given expression,

$tan \theta =\dfrac{\sqrt{3}}{3}\\\\\\tan \theta =\dfrac{1}{\sqrt{3}}\\\\tan \theta =30^o$

Hence, the value of theta is 30°.

<h3>Finding the location of the - tan30°?</h3>

To know that the location of the -tan30°,

$tan30^o = -\dfrac{sin30^o}{cos30^o}$

As the value is negative, therefore, there can be two cases,

Case I: when the value of Sin30° is negative,

Case II: when the value of cos30° is negative.

Case I: when the value of Sin30° is negative,

If the value of Sin30° is negative, while the value of cos30° is positive, the θ will lie in the fourth quadrant.

Case II: when the value of Cos30° is negative,

If the value of Cos30° is negative, while the value of Sin30° is positive, the θ will lie in the second quadrant.

Hence, the value of theta has a 30-degree reference angle and is located in Quadrant II or IV.

Alisa is making bracelets with leather bands. each bracelet uses 7 3/4 inches of leather banding. she plans to make 4 bracelets.

Artyom0805 [142]

Each bracelet is $7 \frac{3}{4} inches$

Turn it into an improper fraction

Multiply 7 and 4 and add 3 which is over 4 which is $\frac{31}{4}$

Multiply by 4 | for each bracelet being made

$\frac{31}{4} * \frac{4}{1}$ $= \frac{124}{4}$

124÷4=31

Answer:

You need 31 inches to make all the braclets
