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:
12-19x8-
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Subtract 20 from both sides:
Divide both sides by -1:
Square both sides:
Subtract 9 by both sides:
Divide both sides by -8:
That means that either a or b is correct and since 9/8 is positive that means it needs to bee less than 9/8 so the correct answer is B
