Circumcenter and circumcirle are shown in the attachment. Assume that the triangle is DEF instead of ABC and that the intersection of perpendiculars is H.
The definition of the circumcenter of a triangle is defined as the point of intersection of all the perpendicular bisectors in the triangle.
The circumcircle passes by all three of the triangle's vertices.
Based on the above, the right choiceS will be:
Point H is the center of the circle that passes through points D, E, and F.
HD = HE
That would be 30C4 - combinations of 4 from 30.
= 30*29*28*27

Answer:
170
Step-by-step explanation:
5/100 ×680
=34
20%=34what about 100%=?
(100×34)÷20
170
A computer discounted at 30% off is less expensive.
First: 1000*.8 = 800
800*.9 = $720
Second: 1000*.7 = $700
