We have to choose the correct answer for the center of the circumscribed circle of a triangle. The center of the circumscribed circle of a triangle is where the perpendicular bisectors of a triangle intersects. In this case P1P2 and Q1Q2 are perpendicular bisectors of sides AB and BC, respectively and they intersect at point P. S is the point where the angle bisectors intersect ( it is the center of the inscribed circle ). Answer: <span>P.</span>
4: 0.99
5: 0.66
6: 0.79
7: 5.2
8: 4.86
9: 4.3
I hope I helped! Also, one thing when you adding decimals or multiplying them, pretend the decimal point isn't even there. Then, once you have your answer, you just add the decimal in the middle. Basically just adding like in first grade! Super easy and I hope I helped!
Answer:
I guess they subtracted a 110 from -110 instead of subtracting from 360
5^2 +12^2= diagonal^2
25+144=d^2
169= d^2
D= 13
