=18
Answer:
D)18
Answer:
What is the perimeter of this square? 149.6 ft
Step-by-step explanation:
37.4 + 37.4 + 37.4 + 37.4
= 4 × 37.4
= 149.6 ft
Answer:
The answer should be 20,000 feet
Step-by-step explanation:
sin 0 =opposite/hypotenuse
sin 30 = AB/AC
sin 30 = 10000/c
c= 10000/sin 30
c=10000/1/2
c=20,000 feet
