For this case we must indicate the cosine of A, of the figure shown. By definition:

Substituting the values we have:

So, we have to:

Answer:
Option D
9514 1404 393
Answer:
(B) 4
Step-by-step explanation:
Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...
3 + 8 = 11
This tells you A = 8, so the top number is 1983, and the middle number is B78.
Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...
1 + 9 + B = <something ending in 4>
We know the something cannot be 04 or 24, so must be 14. Then ...
10 + B = 14 ⇒ B = 4
__
So, the whole sum is ...
1983 +478 = 2461
and the letter values are ...

Answer:
x = 3
Step-by-step explanation:
1.8 - 3.7x = -4.2x + 0.3
add -4.2x to both sides
1.8 - 0.5x = 0.3
subtract 1.8 from both sides
-0.5x = 0.3 - 1.8
-0.5x = -1.5
divide by -0.5 on both sides
x = 3
GREAT JOB!!!! YOU GOT IT!!! =)
