During the age of exploration, primarily ___ explores travels across the Atlantic and pacific oceans and first encountered civilizations in the Americas.

Well it would be European explore such as people from Spain, France, Britain and places like that. There was also Christopher Columbus who was one of the reason for the native Americans being discovered and dying. However there was also Leif Eriksson Who was a Norse explorer that was believed to have led the first European expedition to North America 500 years before Christophers birth.

Explanation:

americans had many intangible advantages. well since the british fought a war far from home military orders, troops, and supplies sometimes took months to reach their destinations, and the british had an extremely difficult objective. they had to persuade the americans to give up their claims of independence, americans had a grand cause: fighting for their rights, their independence and their liberty. this cause is much more just than waging a war to deny independence.

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°
