Solve the following system by any method -8x-8y=0 -8x+2y=-20

iVinArrow [24]

$\fbox{Solution by using Matrix}$

$\text{Linear Equation} = -8x-8y=0 , -8x+2y=-20$

$\text{Rewrite the linear equations above as a matrix}$

$\left[\begin{array}{ccc}8&-8&0\\-8&2&-20\\\end{array}\right]$

$\text{Apply to Row2 : Row2 + Row1}$

$\left[\begin{array}{ccc}8&-8&0\\-8&-6&-20\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}8&-8&0\\0&1&10/3\\\end{array}\right]$

$\text{Note: The matrix is now in echelon form.}$ $\text{The steps below are for back substitution.}$

$\text{Apply to Row1 : Row1 + 8 Row2}$

$\left[\begin{array}{ccc}8&0&80/30\\0&1&10/3\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}1&0&10/3\\0&1&10/3\\\end{array}\right]$

$\text{Therefore, the solution is}$

$x= \dfrac{10}{3} \ \text{and} \ \ y=\dfrac{10}{3}$

What is the measure of angle A please HELP I’ll give you BRAINLIEST

k0ka [10]

Answer:

Option (3)

Step-by-step explanation:

By applying cosine rule in the triangle ABC,

BC² = AC² + AB² - 2(AC)(AB)cosA

5² = 3² + 7²- 2(3)(7)cosA

25 = 9 + 49 - 42cos(A)

25 = 58 - 42cos(A)

cos(A) = $\frac{33}{42}$

A = $\text{cos}^{-1}\frac{11}{14}$

A = 38.21°

A ≈ 38°

Option (3) will be the correct option.
