Answer:
1
Step-by-step explanation:
. It is read as 2 raised to zero. Now let see how to solve such problem For example 3^5 then it means 3×3×3×3×3 = 243 Now back to question Anything raised to zero is always 1 Hence 2^0= 1
Answer:
Given: Line p is parallel to line r.
Alternate exterior angles states that two angles in the exterior of the parallel lines, and on opposite sides of the transversal.
Alternate exterior angles are non-adjacent and congruent.
[ Alternate exterior angles]
Since, Angles are congruent if they have the same angle measure in degrees
....[1] [by definition of congruent Angles]
Linear pair states that a pair of adjacent angles formed when two lines intersect.
therefore, by definition
and
forms a linear pair.
Since, linear pair are always supplementary.
is supplementary to 
Supplementary angles states that two angles are supplementary that means they add up to measure 180 degree.

Substitute the equation [1] in above equation we get;

then, by the definition of supplementary angle ;
is supplementary to 
The answer is 38 it would be 16+(11*2)
The air plane altitude is -54 feet per minute
