Using the image, determine the length of each arc.<br> m RC=<br> m CBR =
Montano1993 [528]

<u>Given</u>:

Given that the measure of ∠CDR = 85°

We need to determine the measure of \widehat{RC} and \widehat{CBR}

<u>Measure of arc RC:</u>

Since, we know that if a central angle is formed by two radii of the circle then the central angle is equal to the intercepted arc.

Thus, we have;

m\angle CDR = m \widehat{RC}

Substituting the values, we get;

85^{\circ} = m \widehat{RC}

Thus, the measure of \widehat{RC} is 85°

<u>Measure of arc CBR:</u>

We know that 360° forms a full circle and to determine the measure of arc CBR, let us subtract the values 360 and 85.

Thus, we have;

m\widehat{CBR}=360^{\circ}-m \widehat{RC}

Substituting the values, we have;

m\widehat{CBR}=360^{\circ}-85^{\circ}

m\widehat{CBR}=275^{\circ}

Thus, the measure of \widehat{CBR} is 275°

Help, I don’t know how to solve this.
NNADVOKAT [17]

Answer: Angles ABD and BAD (B)

Step-by-step explanation: Angles ABD BAD are not congruent angles, since they are the same angles.

Congruent angles are angles that both measure the same in degrees.

In this case, B is your correct answer since that answer has the same angle and not comparing any 2 angles, just the same one.

Hope This Helped, Have A Great Day!

Goods that cost 1/5 of one dollar in the U.S. cost one kroner in Denmark, the real exchange rate would be computed as how many D
hodyreva [135]

Answer:

The amount of Kroner that can be bought from 1/5 of one dollar.

Step-by-step explanation:

We have been given that goods that cost 1/5 of one dollar in the U.S. cost one kroner in Denmark. We are asked to find the the real exchange rate that would be computed as how many Danish goods per U.S. goods.

The real exchange rate tells us how much foreign currency can be exchanged for a unit of domestic currency.

It also tells us that how much the goods and services in the domestic country can be exchanged for the goods and services in a foreign country.

Therefore, the real exchange rate would be the amount of Kroner that can be bought from 1/5 of one dollar.
