Answer:
Step-by-step explanation:
∠AEC ≅ ∠BED as vertically opposite angles
- m∠AEC = m∠BED = 1/2(mAC + mBD), angles between intersecting chords
<u>Substitute values and solve for x:</u>
- 4x = 1/2(120 + 2x)
- 4x = 60 + x
- 3x = 60
- x = 20
<u>Find the measure of AEC:</u>
<u>AED and AEC form a linear pair hence supplementary:</u>
- m∠AED = 180° - m∠AEC<u> </u>
<u>Find the measure of ∠AED:</u>
- m∠AED = 180° - 80° = 100°
Divide 4 7/8 by 3/8:
or 39/8 by 3/8. We can drop the denominators 8 and 8 and find 39/3 = 13.
This guy needs 7 more pieces to end up with 20 pieces.
The distance between them is 4.0.
The equation would be 1.5-(-2.5)=d
Hope that helps ya :)
