Answer:
70.5°
Step-by-step explanation:
22² = (20)²+(18)² - 2(20)(18) cos X
484 = 400 + 324 - 720 cos X
-240 = -720 cosx
1/3 = cos X
= X
X = 70.52877937
Answer:
17.0625
Step-by-step explanation:
Due to order of operations the division and multiplication get done first and the we add the 12
45/X + 63/X= 108/X = Y, X= 108 divided by 2 = y, y=54
The Order of magnitude for the population of the world is not five
