Which best describes the circumcenter of a triangle ?

Answer:
(D)
Step-by-step explanation:
Circumcenter of the triangle is the point at which the perpendicular bisectors of the sides of a triangle intersect and which is equidistant from the three vertices.
From the figure drawn, E is the circumcenter of the triangle at which the perpendicular bisectors of the sides of a triangle ABC intersects and which is equidistant from the three vertices that are A, B and C.
Thus, the option which best describes the circumcenter of a triangle is (D.) the point where the perpendicular bisectors of the three sides of the triangle intersect.

Answer:
x = 3.86
a = 5.86
Step-by-step explanation:
From the triangles attached,
By applying cosine rule in triangle 1,
cos(50)° =
cos(50)° =
x = 6cos(50)°
x = 3.86
Now we apply sine rule in the second triangle,
sin(23)° =
sin(23)° =
a = 15sin(23)°
a = 5.86
