Answer:
a) From 10 to 11, Sarah rode 12 km in one hour. That means her velocity was 12 km/hr.
b) Sarah passed by her home at 12:45.
c) From 12 to 13, Sarah rode 15 km. Thus, her velocity was 15 km/hr. From 13 to 14 she rode 3 km. Thus, her velocity was 3 km/hr.
d) Her average velocity was 12+0+15+3/4, or 30/4 which is 7.5 km/hr.
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°
