What is the arc length of the subtending arc for an angle of 72 degrees on a circle of radius 4?
Nesterboy [21]
We know that

[the length of a circumference]=2*pi*r
for r= 4 units
[the length of a circumference]=2*pi*4--------------> 25.12 units

if a  full circle (360°) has a length---------------------> 25.12 units
 arc for an angle of 72 °---------------------------> X
X=72*25.12/360------------> 5.024 units

the answer is 
<span>the length of the subtending arc for an angle of 72</span>° is 5.024 units

The diagram shows a right triangle with legs that measure 4 and 7.
anyanavicka [17]

Calculate the hypotenuse( h ) using Pythagoras' identity

h =√(4² + 7²) = √(16 + 49) = √65

sinΘ = 4 / √65  ⇒ cscθ = √65 / 4

cosθ = 7/ √65 ⇒ secθ = √65 / 7

tanθ = \frac{4}{7} ⇒ cotθ = \frac{7}{4}
