U . v = |u| |v| cos x
48 = 9*12 cos x
cos x = 48/96 = 1/2
x = 60 degrees answer
Answer:
0.64
Step-by-step explanation:
1.) 1000 = 10×10×10
2.) 640÷10=64
3.) 64÷10=6.4
4.) 6.4÷10=0.64
Algebraically:
13 + (38/60) + (35/3600) = 13. 6431 degrees
If you have a graphing calculator ( I am using a TI-84 plus Silver Edition):
13(press 2nd -> apps -> 1) 38 (press 2nd -> apps -> 2) 35 (press alpha -> +) = 13.6431
