2383x28393=18283 that is the correct
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: an equation is a set of numbers put together within a problem that you are meant to solve in order to receive the final answer.
Step-by-step explanation:
5x-17 and 3x-11 are supplementary angles
They add up to 180 degrees
5x-17 + 3x - 11 = 180
8x - 28 = 180
8x= 208
x= 26
3x-11, 90, and 2y + 5 added together equal 180
3x-11 + 90 + 2y + 5 = 180
3(26) - 11 + 2y + 5 = 90
78 - 6 + 2y = 90
72 + 2y = 90
2y = 18
y = 9
I hope this helps!!!
cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)
