Answer:
Option B. 9.11
Step-by-step explanation:
To find the length of line AB, we must first of all calculate the value of θ as shown in the attached photo.
The value of θ can be obtained as follow:
θ + 39° + 120° = 180° (sum of angles in a triangle)
θ + 159° = 180°
Collect like terms
θ = 180° – 159°
θ = 21°
Thus, we can obtain the length of line AB by using sine rule as illustrated below:
b/Sine B = c/Sine C
b = 16
Angle B = 39°
Sine C = 21°
c =?
b/Sine B = c/Sine C
16/Sine 39° = c/Sine 21°
Cross multiply
c × Sine 39° = 16 × Sine 21°
Divide both side by Sine 39°
c = (16 × Sine 21°) / Sine 39°
c = 9.11
Therefore, the length of line AB is 9.11
Answer:
E = {0, 1, 2, 3)
Step-by-step explanation:
- <u>Integer</u>: a number with no decimal or fractional part, from the set of negative and positive numbers, including zero
- < means less than
- > means more than
E = {0, 1, 2, 3)
has 2 oxygens for every carbon.
will contribute one of each for every molecule. You then have to have an even multiple of
molecules to not end up with an odd number of oxygens.
So if you take
, you should end up with 2 carbons on the RHS.
then has 4 oxygens. 2 of them are already accounted for, so you just need one
to balance out the reaction.
The solution must be larger than 9, because the answer is h=10
So,
2.11 can be written as 2 and 11 hundredths, or
.
is in simplest form.
