Answer:
15 ft
Step-by-step explanation:
Using sinus law
sin(A) /a = sin(B) /b = sin(C) /c
Where smale letters indicate the sides
For this question :
(sin(90)*12)/sin(53)=15
9.58
Sin=opposite/hypotenuse
sin53=12/length of slide
Length of slide=12sin53
=9.58
the correct answer is 17
8
value
B ∩ (A ∪ C)'
It's the B part excluding A and C union. Hence,
(A ∪ C)' ∩ B
