Answer:
We have been given the matrix m as m = [874][205].
We can rewrite this matrix as
\begin{gathered}m=\begin{pmatrix}8 &7&4\\2&0&5 \\\end{pmatrix}\\\end{gathered}m=(827045)
Now, we need to the find m_{12}m12
It means we need to find the entity that is present in the first row and the second column.
From the above matrix, we can see that 7 is in the first row and the second column.
Therefore, we have
m_{12}= 7m12=7

We know that the sum of interior angles in a triangle is 180°. Looking at ΔWYZ, we can write:
? + 75 + 75 = 180
? + 150 = 180
? = 30°
