Divide both sides by -5.5.
simplify -12.1/-5.5 to 2.2.
add 2 to both sides
simplify 2.2 + 2 to 4.2
Answer: d = 4.2
Answer
Step-by-step explanation:
First we gave a name to the side that is common for both triangles, can be Y for example.
Using trigonometric functions we can make a relationship between the two angles that we have and the magnitud of the side.
, Because sin(x)= op/hip
, Because con(x)=ad/hip
Having this equations, we can solve the system and find x
we equal Y and solve
Then we rationalize

You would just replace x with 2 in the part equation and solve for it. So 3(2) - 7. This is equal to -1
PLEASE include a picture so we can answer!!!
3.15+4.5+.6=8.25, which is in the standard form for decimals.
