In order to make point D as the vertex in the construction as triangle ABC, the third arc should cross the second arc.
<h3>What is an arc?</h3>
In Geometry, an arc can be defined as a trajectory that is generally formed when the distance from a given point has a fixed numerical value.
In order to make point D as the vertex in the construction as triangle ABC, you must ensure that the third arc crosses the second arc as illustrated in image attached below.

19. 1,234.6
This is TRUE. The sum of the exterior angles of a pentagon do equal 360°.
Answer:
D. Four
Step-by-step explanation:
The number of attributes for the Employee relation is four namely: EmpID, Name, Dept, Salary.
We said four because it is only four attributes that are defined for the Employee relation, but an instance of the relation can have lesser than four attribute but not more than four attribute.
tan(angle) = opposite / adjacent
tan(x) = 8/10
x = arctan(8/10)
x = 38.7 degrees.
