Answer:
32 (degrees)
Step-by-step explanation:
Triangles AED and ACB share a common angle A.
Two of the corresponding sides have the same ratio: AB=AD+DB=2AD, AC=AE+EC=2AE
Therefore the triangles are similar.
Therefore the corresponding angles are congruent, in particular
∠AED ≅ ∠ACB
∠ECF is just another name for ∠ACB
∠AED ≅ ∠ECF
So their measures must be the same,
m∠AED = m∠ECF = 32°

125*(3*60)=22500
22500+30000=52500
52500:((3+2)*60)=175 (</span><span>words per minute)</span>
Answer:
6, 7, and 8
Step-by-step explanation:
2x/3 + 7 <u>></u> 11
Subtract 7 from both sides
2x/3 <u>></u> 4
Multiply both sides by 3
2x <u>></u> 12
Divide both sides by 2
x <u>></u> 6
6, 7, and 8 are the ones that work
