Using the law of cosines and sines, the measure of angle B is: 38.4°.
<h3>What is the Law of Cosines and Sines?</h3>
Law of cosines is: c = √[a² + b² ﹣ 2ab(cos C)]
Law of sines is: sin A/a = sin B/b = sin C/c
Use the law of cosines to find c:
c = √[12² + 18² ﹣ 2(12)(18)(cos 117)]
c ≈ 25.8
Use the law of sines to find angle B:
sin B/b = sin C/c
sin B/18 = sin 117/25.8
sin B = (sin 117 × 18)/25.8
sin B = 0.6216
B = sin^(-1)(0.6216)
B = 38.4°

Answer:
Samantha would have to watch 4 Movies so x=4
Step-by-step explanation:
Answer:
36.7
Step-by-step explanation:
let angle be x
tan x = 0.8
x = tan⁻¹ 0.8 (use calculator)
x = 36.6598
x = 36.7 (nearest tenth)
We can see that the lines are parallel
Also, we can see that the bottom line segment is the given (it is solid) and the top line segment is congruent to that line.
The answer is C.) a line segment that is congruent to a given line segment
Hope this helps!
