The diagram shows a triangle. 2x 60° 2x What is the value of x? Х=

FinnZ [79.3K]

2x+2x+60=180 because the angles have to add up to 180

So you have

4x+60=180

4x=120

x=30

What is the area of a triangle with vertices (1,0) (5,0) (3,4)

Aleksandr-060686 [28]

Answer:

The area of the triangle is of 8 units of area.

Step-by-step explanation:

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ is given by the determinant of the following matrix:

$A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|$

In this question:

Vertices (1,0) (5,0) (3,4). So

$A = \pm 0.5 \left|\begin{array}{ccc}1&0&1\\5&0&1\\3&4&1\end{array}\right|$

$A = \pm 0.5(1*0*1+0*1*3+1*5*4-1*0*3-0*5*1-1*1*4)$

$A = \pm 0.5*(20-4)$

$A = \pm 0.5*16 = 8$

The area of the triangle is of 8 units of area.

11) Endpoint: (0,4), midpoint (-10, -3) Find the endpoint?

earnstyle [38]

Answer:

(-20,-10)

Step-by-step explanation:

$( - 10 \: \: - 3) = ( \frac{0 + x}{2} \: \: \frac{4 + y}{2} )$

Solve for.x coordinate

$- 10 = \frac{0 + x}{2} \\ - 20 = 0 + x \\ x = - 20$

solve for y coordinate

$- 3 = \frac{4 + y}{2} \\ - 6 = 4 + y \\ - 10 = y$

Write an equation for the translation of y = |x|. 13 units down

olga55 [171]

The idea for transitions for an equation like this is
$y = m|x - h| + k$
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so
$y = |x| - 13$
D. would be your answer
