London, england experiences mild weather for what reason? it is farther south than any city in north america, so its climate is warmer. it is close to the atlantic ocean, where strong currents bring warm weather. it is on low land surrounded by mountains, so it is protected from cold ocean winds. it is near the equator, so its climate is about the same year-round.

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°

the answer would be a i think?
