The length of one leg of the right triangle is 5√10
<h3>How to find the leg of a right triangle?</h3>
The leg of a right triangle can be found as follows;
Therefore, using trigonometric ratios,
sin 45 = opposite / hypotenuse
sin 45 = x / 10√5
1 / √2 = x / 10√5
cross multiply
10√5 = x√2
divide both sides by √2
x = 10√5 / √2
x = 10√5 / √2 × √2 / √2
x = 10√10 / 2 = 5√10

Answer:
r ≈ 22.44 ft
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ), then
141 = 2πr ( divide both sides by 2π )
= r , that is
r ≈ 22.44 ft ( to the nearest hundredth )
