Answer: 59.04
Step-by-step explanation:
tan 16= x/200
tan16/1=x/200
200 tan 16=x
x=57.349077...
x=57.349077...
Add 1.69, the distance from the ground to her eye:
57.349077...+1.69=
59.039077...
≈ The skyscraper is 59.04 meters tall.

Answer:
-16
Step-by-step explanation:
Subtract all the numbers to get -112.
To find the mean (average) you need to divide by the amount of values in your data set, in this case 7.
-112 ÷ 7 = -16
Answer:
∠RQS = 100°
Step-by-step explanation:
The angles 5x + 5 and 11x - 65 form a linear pair. That is they sum to 180°
Sum the 2 angles and equate to 180, that is
5x + 5 + 11x - 65 = 180
16x - 60 = 180 ( add 60 to both sides )
16x = 240 ( divide both sides by 16 )
x = 15
∠RQS = 11x - 65 = (11 × 15) - 65 = 165 - 65 = 100°
