We have that since the chords are equal, the arcs are equal too. Hence AB=RS. We also have that AB=AR+RB and RS=RB+BS. By equating these two, we have that AR=BS. Hence BS=55 degrees. Substituting back, since we know RB and BS, we get: RS=55+66=121 degrees
Answer:
C) $826.82 to $873.18.
Step-by-step explanation:
Sample mean (M) = $850
Standard deviation (s) = $54
sample size (n) = 36
Z for 99% confidence interval (Z) = 2.576
The confidence interval is determined by the following relationship:
![M \pm Z*\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=M%20%5Cpm%20Z%2A%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
Applying the given values, the lower (L) and upper (U) values are:
![850 \pm 2.576*\frac{54}{\sqrt{36}}\\L=\$826.82\\U=\$873.18](https://tex.z-dn.net/?f=850%20%5Cpm%202.576%2A%5Cfrac%7B54%7D%7B%5Csqrt%7B36%7D%7D%5C%5CL%3D%5C%24826.82%5C%5CU%3D%5C%24873.18)
The answer is C) $826.82 to $873.18.

Step-by-step explanation:
Answer:sinA=8/17
Step-by-step explanation:
Using Pythagoras principle
x=√(15^2+8^2)
x=√(15x15+8x8)
x=√(225+64)
x=√(289)
x=17
SinA=opposite/hypothenus
SinA=8/17
