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°
The equation in its standard form is written as followsax ^ 2 + bx + c = 0
To find the values of a, b, c we must compare the given equation with the standard equation. Comparing we have:
ax ^ 2 + bx + c = 0
1 / 4x ^ 2 + 5 = 0
Therefore the values of a, b, c are
a = 1/4
b = 0
c = 5
