Answer:
39,000
Step-by-step explanation:
The height of the Washington monument is 555.146.
I got this by using trigonometry “tan(77) • 118”
A line adds up to equal 180 degrees. And adjacent angles also add to equal 180 since they share a side on a line. So add them together and make them equal 180
9x - 7 + 8.5x + 4 = 180
17.5x - 3 = 180
17.5x = 183
x = 10.5
