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°
Answer:
50/3
Step-by-step explanation:
For x
3x-2(2+1)=4
3x-2(3)=4
3x-6=4
3x=4+6
3x=10
x=10/3
as we have to find 5x=?
5(10/3)
50/3
Answer:
V≈4.19ft³
Step-by-step explanation:
The volume of a sphere with a radius of 1 foot is 4.19ft³.
In order to find this:
V=4
3πr3=4
3·π·13≈4.18879ft³
Answer:
y=27
Step-by-step explanation:
x = k/y
9 = k/6
k = 54
so
2 = 54/y
y= 27
