Hey you, i don’t think anyone can answer that with that little info...
19.2
To find the hypotenuse the equation would be: a^2 + b^2 = c^2.
12 squared is 144 and 15 squared is 225. Add them and you get 369. Then, square root 369 to isolate c. It'd be about 19.2
TRiangles ABE and ACD are similar because BE and CD are parallel.
Therefore CD / BE = AD / AE
8 / BE = 16 / 10
BE = 8*10 / 16 = 5
Also, 16 / 10 = AC / AB = 20 / AB
AB = 10 * 20 / 16 = 12,5
Perimeter of ABE = 5 + 10 + 12.5
= 27.5 units (answer)
