Ответ:
so
TW/VW = UW/TW
12/8 = UW/12
UW = 12 * 12 / 8
UW = 144/8
UW = 18
answer
C. 18
Ответ:
VT = sqrt(12^2 + 8^2) = 14.4222 ( round to 14.42)
Angle V = cos^-1(8/14.42) = 56.3099 degrees ( round to 56 degrees)
angle T = 180-90-56 = 34 degrees , 90-34 = 56
UW = tan(56) x 12 = 17.79
round to 18
answer is 18
Ответ:
