What are the dimensions of the matrix?. i need help pls
1 answer:
Answer:
5 X 5
Step-by-step explanation:
The dimensions of a matrix number of rows and columns of that matrix. If it is as an
(read as
by
it means that it has
number of rows and
number of columns.
In the given problem, the rows and columns are 5. So, we write it is a matrix. We call it a Square matrix, since the number of rows equals the number of columns.

Answer:
12 or 103
Step-by-step explanation:
The given angle is opposite the shorter side, so there will be two solutions.
In order to find f, we need to know angle F. We can find that by first finding angle E.
E = arcsin(e/d·sin(D)) = arcsin(71/62·sin(36°)) = 42.307° or 137.693°
F = 180° -D -E = 180° -36° -{42.307°, 137.693°} = {101.693°, 6.307°}
Then the measure of f is ...
f = sin(F)/sin(D)×d = 62/sin(36°)×sin({101.693°, 6.307°})
f = {103.29, 11.59}
Side f is either 12 or 103.
