K-263.48=381.09
we add 263.48 on both sides
k=644.57
Answer:
124°
Step-by-step explanation:
cos X = (11²+7²-16²)/2(11)(7)
= (121+49-256)/154
= -86/154
= -0.5584
X = cos~¹ -0.5584 = 124°
Answer:
x = 14.
Step-by-step explanation:
The other 2 opposite angle are both equal to 70 degrees.
So 5x = 70
x = 70/5
= 14 degrees.
Answer:
8.
Step-by-step explanation:
91-35=56
56/7=8
1 second = 5.8x10^6 mg
60 seconds = 5.8x10^6 x 60 = 3.48x10^8 mg
(i.e 3.48x10^8 mg/minute)
1000 mg = 1 g
3.48x10^8 mg = 3.48x10^8/1000 = 3.48x10^5 g
Therefore, 5.8x10^6 mg/s = 3.48x10^5 g/min
