5y + 7 = 52
5y = 52 - 7
5y = 45
y = 9

=

=
3(x+12) = 2 x 42
3x + 36 = 84
3x = 84 - 36
3x = 48
x = 16
Angle H = 180 - 52 - 36 = 92
Answer:
The correct option is (a).
Step-by-step explanation:
The vertices are equidistant from the circumcenter.
Circumcenter of a triangle is a point where the perpendicular bisectors are intersection each other.
In figure (a) the point P is the intersection point of all perpendicular bisector, therefore point P is the circumcenter of triangle ABC and the point P is equidistant from A,B and C.
Therefore option (a) is correct.
In figure (b) the point P is the intersection point of all perpendicular, therefore point P is not the circumcenter of triangle ABC.
Therefore option (b) is incorrect.
In figure (c) the point P is the intersection point of all bisectors, therefore point P is not the circumcenter of triangle ABC.
Therefore option (c) is incorrect.
In figure (d) the point P is the intersection point of all medians, therefore point P is not the circumcenter of triangle ABC.
Therefore option (d) is incorrect.

Answer:
P = 44
Step-by-step explanation:
The formula for the perimeter (circumference) of a circle is;
C = πd
C = 2πr
C = 2π (3.5)2
C = 2π7
C = 2 * 22/7 * 7
C = 2 * 22
C = 44
