Answer: you can't further simplify 2x+45
CommentThe measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.
= 49
To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.
= 360 - 49 - 107 = 204
=
+
Arc(
ABC) = 204 + 49 = 253
Arc(
BAC) = Arc(BC) + Arc(AB)
Arc(
BAC) = 107 + 49
Arc(
BAC) = 156
Arc(
ACB) = 107 + 204 = 311
A)1,5 b)2,6 c)3,8 d)4,10 e)5,13
Make them y = mx + b
4y = 3x + 6
y = 3/4x + 6/4
3y = -4x + 6
y = -4/3x + 2
They have opposite sign and reciprocal slope so they are perpendicular
Answer: perpendicular and intersect
