Because of the completion of the panama canal, approximately how much time was saved when traveling between new york city and san francisco?
a. 2 weeks
b. 2.5 months
c. 4 weeks
d. 4.5 months

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°

there is no chart here so no one can answer this.
