Answer:
Step-by-step explanation:
c^2=a^2+b^2-2abcosC
cosC= (a^2+b^2-c^2)/(2ab)
C=arccos[(a^2+b^2-c^2)/(2ab)]
C=arccos(90^2+55^2-50^2)/(2(90)55)
C=arccos(8625)/(9900)
C=29.4 degrees
The answer would be 2431.
Answer:
x > 3
Step-by-step explanation:
16x + 8 > 12x + 20 <== subtract 12x from both sides
- 12x - 12x
4x + 8 > 20 <== subtract 8 from both sides
- 8 - 8
4x > 12 <== divide both sides by 4
/4 /4
x > 3
This means that x is any value that is greater (bigger) than 3.
Hope this helps!
The answer is D.
The first one says you add -4 each time in the sequence.
The second says you add -2 each time in the sequence.
The third says you multiply by -2 each time in the sequence.
The fourth says you multiply by -4 each time in the sequence.
-2*-4=8
8*-4=-32
