Applying the law of sines, the approximate length of side YZ is: A. 15.7 units.
<h3>How to Apply the Law of Sines?</h3>
Law of sines is expressed as follows: x/sin X = y/sin Y = c/sin Z.
Given the following:
- x (YZ) = ?
- X = 32°
- z = 24
- Z = 180 - 32 - 94 = 54°
Plug in the values
x/sin 32 = 24/54
x = (sin 32 × 24)/sin 54
x ≈ 15.7 units.

Answer:what is the least common denominator of the fractions 2/3 and 3/5? HELP PLEASE
Step-by-step explanation:
Make more than a 80 on quizzes and you should be fine 75 lowest possible
so we have the points of (0,-7),(7,-14),(-3,-19), let's plug those in the y = ax² + bx + c form, since we have three points, we'll plug each one once, thus a system of three variables, and then we'll solve it by substitution.
well, from the 1st equation, we know what "c" is already, so let's just plug that in the 2nd equation and solve for "b".
well, now let's plug that "b" into our 3rd equation and solve for "a".

Answer:
4 pairs of sock and a little bit of left over change.
Step-by-step explanation:
24.95 + 5.95x = 50
-24.95 -24.95
5.95x=25.05
/5.95 /5.95
x = 4.21
We drop the 0.21 because you cant have 0.21 pairs of socks and we get:
x=4
