which clause is an independent clause?

because the earth is always rotating

the winter in norway is long and harsh

while the horse slowly chewed on some hay

since summertime can be equally difficult

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°

would not cooperate with each other voluntarily.
