Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = 
and tan x = 
thus
+ tanΘ × cosΘ
= 
+ 
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
Answer:
f = 4
Step-by-step explanation:
60= 15f
divide both side by 15
f = 4
Answer:
32pi
Radius=1/2 Diameter
radius=2
Area of circle= pi*radius^2= 4pi
4pi*8=32 pi
