Explanation:

For #1 what ever the image shows that's what u describe (the coast, mountains) ecs. And for #2 The Pyramids. duh

#3 Because if a natural land form (water).

escalation means to increase in intensity, extent, or amount.

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°
