Answer:

8\sqrt{2}\ units.

Step-by-step explanation:

Use the trignometric property.

sin\theta = \frac{Perpendicular}{Hypotenuse}

Perpendicular = 8

Hypotenuse = h

\theta = 45^{\circ}

sin\ 45^{\circ} = \frac{1}{\sqrt{2}}

\frac{1}{\sqrt{2}} = \frac{8}{h}

h = 8\sqrt{2}\ units

Hope I helped you! x

Solve the equation
inysia [295]

Answer:

x ≈ 1.32, x ≈ - 5.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± \sqrt11} ( subtract 2 from both sides )

x = - 2 ± \sqrt{11}

Thus

x = - 2 - \sqrt{11} ≈ - 5.32 ( to 2 dec. places )

x = - 2 + \sqrt{11} ≈ 1.32 ( to 2 dec. places )

Use the Echelon Method<br> 1. Solve<br> x + 3y = 7<br> 3x + 4y = 11
Ludmilka [50]

Answer:

x = 1     y = 2

Step-by-step explanation:

x + 3y = 7

- Subtract x from both sides.

3y = -x + 7

- Divide both sides by 3 to isolate the variable.

y = -1/3x + 7/3

- Plug the value of y into the other equation.

3x + 4(-1/3x + 7/3) = 11

3x - 4/3x + 28/3 = 11

- Add like terms.

5/3x + 28/3 = 11

5/3x = 5/3

x = 1

- Plug the value of x into the equation.

x + 3y = 7

(1) + 3y = 7

3y = 6

y = 2
