Answer: b = 3
Step-by-step explanation:
7.7278 g/ml is the most accurate density of the substance.
<h3>What is density?</h3>
It is define as the quantity per unit volume, unit area, or unit length.
i.e. the mass of a substance per unit volume.
Mathematically,
----- equation (1)
Where,
p is the density
m is the mass
v is the volume
According to the question,
Mass = 27.82 grams
Volume = 3.6 ml
By substituting the Value of m and v in equation 1.


Therefore,
The most accurate density of the substance in g/ml is 7.7277777 g/ml.

X + x + 2 = 90
2x + 2 = 90
-2. -2
to combine like terms
2x = 88
Divide both sides by 2 to isolate x
x = 44
Answer
A is x+2 = 46
B is x = 44
Total 90 degrees = complementary angle
