WebWhich simplifies to: cos A = x 2 − x 1 ( x 2 − x 1) 2 + ( y 2 − y 1) 2. Therefore the angle is: A = cos − 1 ( x 2 − x 1 ( x 2 − x 1) 2 + ( y 2 − y 1) 2) I'm sorry if this was overly complicated for the question. There probably is some simpler way to do it, but it will look a lot less messy once you plug in the numbers.

WebMar 8, 2024 · Whenever you see an angle on the arc of a circle, this means that the two points are separated by that angle: in this case, A and B are separated by an angle of º 100 º. If º ∠ B F C + ∠ A C F = 180 º, then B F is parallel to A C (these would be co-interior angles, if you're curious). Therefore, we have to find ∠ B F C and ∠ A C F ... speedy florenceWebAngle BCD and angle BAE are inscribed angles on the same arc. So, angle BCD = BAE = 44.5°.
