Answer:

X=13

Step-by-step explanation:

So if ΔABC ≅ ΔDEC, then that means that ∠B is ≅ ∠E. Therefore you would write the equation 3x=6x-39 and solve for X to get 13.

How can you describe the line that passes through (0,3) and (-1, 0)​
julia-pushkina [17]

let's find the equation of line passing through those two points.

slope of the given line :

  • \dfrac{y_2 - y_1}{x_2 - x_1}

  • \dfrac{3 - 0}{0 - ( - 1)}

  • \dfrac{3}{ 1}

  • 3

now, let's plug the value of slope (m)

and y - intercept (c) in general equation

of line in slope intercept form.

i.e y = mx + c

so, we get the equation of given line as :

  • y = 3x + 3

What is the length of the altitude of the equilateral triangle below
ale4655 [162]
Using Sine.

Sine = Opposite / Hypotenuse

sin 60° = a / (6√3)                        But sin60° = √3/2

√3/2 = a/(6√3)

Cross multiply

2*a = 6√3 * √3

2a = 6 * √(3*3)

2a = 6*3

a = 6*3/2

a = 3*3 = 9

Option E.

Hope this helps.
