Answer A
Step-by-step explanation:
Angle A = 180 - 26 - 90 (90 right angle)
The cosine of an angle is equal to the ratio of the adjacent side to the hypotenuse.
cos ( A)= adj/hyp
Cos (26) = a / 13
a = 13* Cos (26)
a= 11.7
Find the last side of the triangle using the Pythagorean theorem.
Answer:
diameter = 8 miles
Step-by-step explanation:
Area of a circle = πr²
πr² = 50.24
3.14*r² = 50.24
r²=
r² = 16
r² = 4²
r=√4²
r = 4 miles
diameter = 2 *radius = 2*4 = 8 miles
