The next step she should take is to draw arcs above and or below line AB to show where the triangles sides meet.
<h3>Steps in construction of an equilateral triangle</h3>
The steps involved in the construction of an a equilateral triangle are:
- Place the compass point on A and measure the distance to point B
- Swing an arc of this size above or below of the segment.
- Do not change the span on the compass
- Then place the compass point on B and swing the same arc, intersecting with the first arc
- Label the point of intersection as the third vertex of the equilateral triangle.
Thus, the next step she should take is to draw arcs above and or below line AB to show where the triangles sides meet.

Answer:
sorry dont know
Step-by-step explanation:
Answer:
y = -1/3x -3
Step-by-step explanation:
-2x - 6y = 18
We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept
Add 2x to each side
-2x-6y +2x = 2x+18
-6y = 2x+18
Divide each side by -6
-6y/-6 = 2x/-6 + 18/-6
y = -1/3x -3
This is in slope intercept form with the slope -1/3 and the y intercept -3
You have two 30-60-90 triangles, ADC and BDC.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC
First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30
Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10
AB = AC - BC = 30 - 10 = 20
Step-by-step explanation:
6+ 7•log2 x = 21
7.log2 x = 21-6
7. log2 x = 15
log2 x = 15/7
x = 2^(15/7)
x = 4.416 = 4.42
