Answer:

Step-by-step explanation:

Find all the angles of the triangle.

A straight line is 180° therefore you do 180°-105°=75°

All the angles in the triangle added together is 180°.

Now you write it into an equation,

55+75+x=180

x=180-130

x=50°

What is X if

umka2103 [35]

Answer:

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Step-by-step explanation:

$\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}$

$X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}$

$X = \begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}$

$X = \begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}$

Multiplication property of Equality. I tried my best to decipher the text you added, and it seems to me like you end up multiplying both sides of the equation by 8/3. This is the reciprocal of 3/8, so multiplying them together leaves you with -x. When 48 is multiplied by 8/3 you get 128, so x=-128. The Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal.
