When you're converting from a smaller unit to a larger unit, divide.
When you're converting from a larger unit to a smaller unit, multiply.
Answer: The null and the alternative hypotheses are given below:


Under null hypothesis, the test statistic is:




Now we have to find the left tailed critical value at 0.01 significance level using the standard normal table.
The critical value is:

Since the test statistic is -0.26 lies in acceptance region because the critical region is beyond -2.33, therefore, we fail to reject the null hypothesis.
First, you have to apply the Pythagorean Theorem to this problem to solve for the hypotenuse.
22^2 + 15^2 = c^2
"C", which is the hypotenuse, is approximately 26.63 inches long. So, now add all the sides, and you should have 63.63 inches as your final answer.

Step-by-step explanation:
the law of sines :
a/sin(A) = b/sin(B) = c/sin(C)
with the sides being opposite to the angles.
so,
14/sin(80) = x/sin(60)
x = 14×sin(60)/sin(80) ≈ 12.3cm
