Answer:
x = 38°
Step-by-step explanation:
in the given question,
the two angles are complementary, because sum of their measures = 90°
so,
=》52° + x = 90°
=》x = 90° - 52°
=》x = 38°
Answer:
-63
Step-by-step explanation:
5×9 = 45
45/-5 = -9
-9×7 = -63
That is, only real numbers can be used in the domain, and only real numbers can be in the range. There are two main reasons why domains are restricted. You cannot divide by 0 . You cannot take the square (or other even) root of a negative number, as the result will not be a real number.
Scientist look at various evidence like fossils, rocks, and glaciers to determine what it is like millions of years ago. Evidence like rocks, movement of the tectonic plates and glaciers can determine the landforms and climate of an area. Evidence like fossils, combined with the current knowledge of evolution and the climate at that time allows scientists to hypothesize what it looks like millions of years ago.
Matrix dimension 4x4. We put 1 if role is in relation with the collon (role is first number of (a,b), number a, and collone is number b. We have them 4). So, the matrix representation is:
0 0 1 1
0 1 0 0
0 1 0 0
0 0 0 0
