Answer:
c/e = e/d
Step-by-step explanation:
These are similar triangles. When you flip the larger one clockwise to enable you to see which sides are corresponding, then you find that:
c corresponds to e'
a corresponds to b
e corresponds to d
Therefore, c/e in the original position = e'/d in the flipped position.
<u>So c/e = e/d</u>
Answer:
It would be the side opposite the smallest angle.
Side DE (which is opposite angle F) is the shortest.
Step-by-step explanation:
Answer: 35
the age of Roberto is x (x > 3)(x ∈ N)
because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3
in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4
because In 7 years the sum of their ages will be 81 =>
x + 7 + x + 4 = 81
⇔ 2x + 11 = 81
⇔ 2x = 70
⇔ x = 70/2 = 35
=> the age of Roberto is 35
