Answer:

The Correct Answer is option D.

Step-by-step explanation:

Tina observed that the temperature was 72 degrees. Later the temperature rose 21 degrees and then dropped 11 degrees.

 

That is, 72+21-11=82.

 

She then flew to New York where the temperature was 67 degrees.

 

The change in temperature from when Tina left Atlanta and arrived in New York is,

82-67=15.

 

Hence, the change in temperature is 15.

 

Thus, the correct option is D.

Cassandra assigns values to some of the measures of triangle ABC. If angle A measures 30°, a = 6, and b = 18, which is true?
Anna [14]

Answer:

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b

Step-by-step explanation:

we know that

step 1

Find the measure of angle B

Applying the law of sines

\frac{sin(A)}{a}=\frac{sin(B)}{b}

we have

A=30\°

sin(30\°)=1/2

a=6\ units

b=18\ units

substitute

\frac{(1/2)}{6}=\frac{sin(B)}{18}

\frac{1}{12}=\frac{sin(B)}{18}

sin(B)=\frac{18}{12}

sin(B)=\frac{3}{2}=1.5

Remember that the value of sine can not be greater than 1

therefore

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b
