Answer:
OH²=412
Step-by-step explanation:
A Circumcenter of a triangle is the point where the three perpendicular bisectors of a triangle meet.
The Orthocenter is the point where all three altitudes of the triangle intersect.
Given any triangle, the orthocenter, circumcenter and centroid are collinear on the Euler line. By Euler's Identity, the distance between the circumcenter and the orthocenter of a triangle is related to the circumradius(R) and the sides(a,b,c) of the triangle by the relation
OH²=9R²-(a²+b²+c²)
R=7, a²+b²+c²=29
OH²=9(7)²-29
OH²=412
1.) Group like terms: 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x-5+7
2.) Add similar elements: = 4x+3x-5x+5x+5x-3x+2x-8x+2x-5x=0
3.) =-5+7
4.) Add/Subtract the numbers: -5 + 7 = 2
<u>Your Answer: 2</u>
