Aman standing on the roof of a building 58.0 feet high looks down to the building next door. he finds the angle of depression to the roof of that building from the roof of his building to be 34.8°, while the angle of depression from the roof of his building to the bottom of the building next door is 63.3°. how tall is the building next door? (round your answer to the nearest tenth.)

Measures of the angle of r, 31 s (x+4) t (3x+9)

Me. i can't figure out this question. give an explanation too. .

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
