An estuary is where salt water and fresh water meet. Estuaries are usually found at the edge of the coast, where the ocean water, or salty water, meets river, lake, any fresh water source, water.
A tributary is something completely different. It is a, usually smaller than the main river or lake, river/stream stemming off a bigger river or lake, or flowing into that river or lake.

The answer is A.
Ice Age or glacial period refers to the extended period of well-below-average temperatures. It is a prolonged period where reduction in the temperature of the Earth’s surface and atmosphere are caused by the expansion of continental and polar ice sheets and alpine glaciers. Usually this phenomenon occurs in the northern and southern hemispheres where extensive ice sheets are seen most.

Answer:
m<E = 105°
Explanation:
The ratio of the corresponding side lengths of ∆STU and ∆DEF are equal. That is:
.
According to similarly theorem, if two ∆s are similar, the ratio of their corresponding lengths would be the same. Therefore, ∆STU is similar to ∆DEF.
Since ∆STU ~ ∆DEF, their corresponding angles are congruent. That is:
<S ≅ <D, this means both are 29° each.
<T ≅ <E, this means they are both equal
<U ≅ <F. this means both are 46° each.
Thus:
m<E = 180 - (m<D + m<F) (sum of ∆)
m<E = 180 - (29 + 46) (substitution)
m<E = 180 - 75
m<E = 105°
