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.

Step-by-step explanation:
Given : 
Since the alternative hypotheses is right-tailed, so the test is a right-tailed test.
Sample size : n=30
The degree of freedom for t-distribution= 
The by using the normal t-distribution table , we have
The P-value corresponds to t-statistic vale 2.43 and degree of freedom 29 , is 0.01075997 i.e. approximately 0.0108
