The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
Step-by-step explanation:
0.000672, 6.72×10⁵, 67.2×10‐⁴, 672×10⁴
The approximate length of side AB is 14.0. The correct option is B. 14.0 units
<h3>Law of sines </h3>
From the question, we are to determine the measure of side AB
First, we will determine the measure of angle A
A + B + C = 180° (<em>Sum of angles in a triangle</em>)
A + 65° + 35° = 180°
A = 180° - 65° - 35°
A = 80°
Now, using the law of sines
c/sinC = a/sinA
c = AB
a = BC = 24
Thus,
c/sin35° = 24/sin80°
c = (24×sin35°)/sin80°
c = 13.978
c ≈ 14.0
∴ AB = 14.0
Hence, the approximate length of side AB is 14.0. The correct option is B. 14.0 units

Answer:
49mg
Step-by-step explanation:
let's call every 7 mg of fever reducer a "dose"
Divide the weight of Greg by the weight per "dose"
42/6 = 7 doses
Each "dose" is 7mg. Multiply the number of doses by 7mg.
7 dose X 7mg = 49mg
Therefore, if Greg weighs 42kg, the pediatrician will prescribe 49mg of fever reducer.
