hello :
<span>Cot(pi/2-x)= tanx
</span><span>Cot(pi/2-x)/Cosx = tanx/cosx =tanx ×(1/cosx) = tanx ×secx
</span>because 1/cosx = secx
Answer:
1.5
Step-by-step explanation:
You have the same volume which is 24pi. You divide 24 by 16 and get 1.5
To solve this problem, we can use cross multiplication:
First, we can to convert inches into feet so...
5 inches = 0.416667 ft
7 inches = 0.583333 ft
(0.416667 ft/ 0.583333 ft) = (12 ft/ x ft)
x = 16.8 ft
So the actual width is 16.8 ft.
Hope this helps!
Angle: x
complement: 90-x
3x=90-x-14
4x=76
x = 19
90-x= 71
