Use the markings in the image to answer the following questions (drawing not to scale): [image attached]

a. As you look at sides and , which side lengths are possible to calculate based on the information in the image?
b. For those side lengths which are possible to calculate, what steps would you take to calculate each side?
c. For those side lengths we don’t have enough information to calculate, what information would you need to complete the calculations?

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
