Step-by-step explanation:
a. Area = 121 ft²
s² = 121
s = √121
Therefore s = 11 ft
b. Area = 81 yd²
s² = 81
s = √81
Therefore s = 9 yd
c. Area = 324 cm²
s² = 324
s = √324
Therefore s = 18 cm
d. Area = 361 mi²
s² = 361
s = √361
Therefore s = 19 MI
Answer 5 because cos(60) x 10 = gives 5
Answer:
25°
Step-by-step explanation:
the arcs are congruent, and the radii are the same length, as it would be from any other point in a circle. this means that the angle must be the same.
