angle C is a right angle and given the conditions c=2 B= 45 degrees, solve for the side lengths of the right triangle

1 answer:

8 0

Since the triangle is 45,45,
90 arrangement. We can use the special triangle trick. Which gives us 2,2 and square root of 2 times 2

What is the product?

victus00 [196]

Answer:

$\begin{bmatrix}-2\\0 \end{bmatrix}$

Step-by-step explanation:

We have the product, $2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

It is known that,

'When we multiply a scalar with a matrix, the scalar is multiplied by each element of the matrix'.

So, we get,

$2\times \begin{bmatrix}-1\\0 \end{bmatrix}$ .

⇒ $\begin{bmatrix}-1\times 2\\0\times 2 \end{bmatrix}$

⇒ $\begin{bmatrix}-2\\0 \end{bmatrix}$

So, the resulting product is $\begin{bmatrix}-2\\0 \end{bmatrix}$ .

Which equation represents a circle that contains the point (-5, -3) and has a center at (-2, 1)?

Evgen [1.6K]

The equation (x + 2)² + (y - 1)² = 25 represents a circle that contain the point (-5 , -3) and has a center at (-2 , 1)

Step-by-step explanation:

The equation of a circle of center (h , k) and radius r is:

(x - h)² + (y - k)² = r²

The given is:

The center of the circle is (-2 , 1)
The circle passes through point (-5 , -3)

The length of the radius is the distance from the center of the circle

to a point on the circle

∵ The formula of the distance is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∵ The center of the circle is (-2 , 1)

∵ The circle passes through point (-5 , -3)

∴ $r=\sqrt{[(-5)-(-2)]^{2}+[(-3)-(1)]^{2}}$

∴ $r=\sqrt{[-3]^{2}+[-4]^{2}}$

∴ $r=\sqrt{9+16}$

∴ $r=\sqrt{25}$

∴ r = 5

∵ The equation of the circle is (x - h)² + (y - k)² = r²

∵ The center of the circle is (-2 , 1)

∴ h = -2 and k = 1

∵ r = 5

∴ r² = (5)² = 25

- Substitute the values of h , k , r² in the equation of the circle

∴ (x - -2)² + (y - 1)² = 25

∴ (x + 2)² + (y - 1)² = 25

The equation (x + 2)² + (y - 1)² = 25 represents a circle that contains

the point (-5 , -3) and has a center at (-2 , 1)

A line passes through the point (6, - 9) and has a slope of 4/3 Write an equation in slope-Intercept form for this line.

Nostrana [21]

Answer:

4x-3y-51=0

Step-by-step explanation:

y- $y_{1}$ =m(x- $x_{1}$ )

y-(-9) = $\frac{4}{3}$ (x-6)

3y+27=4x-24

4x-3y-51=0
