well, we can say that 1 hour is 100%, what is 2/5 hr off of it in percentage?

X divided by three equals nine SO to find x you would multiply three times nine
Answer:
11). x = 25.8°
12). x = 67.3°
Step-by-step explanation:
11). By using sine rule in the given triangle,
cos(x) = 
cos(x) = 
x = 
x = 25.84
x ≈ 25.8°
12). By applying tangent rule in the given triangle,
tan(x) = 
tan(x) = 
x = 
x = 67.29°
x ≈ 67.3°
12 is the answer
hope this helps!
