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°

now, the angle of θ, can only have a "y" value that is positive on, well, y is positive at 1st and 2nd quadrants
and "x" is positive only in 1st and 4th quadrants
now, that angle θ, can only have those two fellows, "y" and "x" to be positive, only in the 1st quadrant, and also both to be negative on the 3rd quadrant.
and that those two fellows, can also be both negative in the 3rd quadrant
3/1 = 3, and -3/-1 = 3
so, the solutions can only be "3", when both "y" and "x" are the same sign, and that only occurs on the 1st and 3rd quadrants
Answer:
10x-15
Step-by-step explanation:
First, do Abbey. Abbey= 5 hrs less than 3 Emily.
Nathan spends twice as much as Abbey. Then you get 3x (Emily is x) -5 +x (for Emily) +6x - 10 (for Nathan. Add those. You get 3x+x+6x-5-10. I hope this is correct.
D : because this make so much since duh . && watch yuu get it right !
