Which expression gives the value of QR?

Mathematics
1 answer:
Montano1993 [528]1 year ago
8 0

Answer:

B

Step-by-step explanation:

using the Sine Rule in Δ QRS

\frac{QR}{sinS} = \frac{RS}{sinQ} ( substitute values )

\frac{QR}{sin52} = \frac{67}{sin80} ( cross- multiply )

QR × sin80° = 67 × sin52° ( divide both sides by sin80° )

QR = \frac{67sin52}{sin80}

The six numbers in a set are 137, 128, 250, 136, 129, and 138. Which measures of the data increase when the outlier is included?
Leni [432]
Range increases. This is because range is the biggest number minus the smallest number. So when the biggest number is much bigger than the rest of the numbers, the range increases.
