Answer:
78
Step-by-step explanation:
Angle W:
180 = 90 + 57 + W
180 = 147 + W
W = 33 degrees
Using trigonometry functions to find the side lengths. (SOH CAH TOA)
Side XZ:
cos(57) = XZ / 18
XZ = cos(57) x 18
XZ = 9.8 units
Side XW:
sin(57) = XW / 18
XW = sin(57) x 18
XW = 15.1 units
Hope this helps!! :)
The x would equal 0 and the y would equal 3
The answer would be (A) 6
9/17 = .529411...
8/45 = .17777 (the seven repeats)
17/9 = 1.8888 (the eight repeats)
16/90 = .17777 (the seven repeats)
While B and D both equal approximately 1.7. B is the simplified form, So B is the answer
Brainliest would be fantastic :) Have a nice day.
