Answer:
2π
Step-by-step explanation:
Period is the time it takes for the wave to reach one full cycle, which is the distance between the adjacent crests. The first crest is at 0 and the second crest is at 2π. Therefore, it takes 2π seconds to complete a full cycle. Hope this helps!
Answer:
she will need the other 75%
Step-by-step explanation:
x=180°-109°=71° (Interior angles)
y= 71° (Alternate angles)
y= 180°- 65°=115° (Adjacent angles)
x= 65° (Corresponding angles)
