Point h is the circumcenter or a triangle def which must be true

The correct options are 1, 3 and 6.

Step-by-step explanation:

Circumcenter of a triangle:

1. It is the intersection point of perpendicular bisector of at least two sides of the triangle.

2. It is the center of the circle that passes through all vertices of the triangle.

It is given that the H Is the circumcenter or a triangle DEF. It means H is the center of the circle that passes through the points D,E,F.

Option 1 is correct.

HD,HE and HF are radius of the circle,

Option 3 is correct.

Option 6 is correct.

Therefore the correct options are 1, 3 and 6.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

(3x-8) or (3x+8)
