Answer:AC = 20
BK = 9.6
Step-by-step explanation:
AC is found using the Pythagorean theorem in the usual way:
AC² = AB² + BC²
AC² = 12² + 16² = 144 +256 = 400
AC = √400
AC = 20
You may recognize this is a 3-4-5 triangle scaled by a factor of 4.
__
Then BK is found using similar triangles. All of the triangles in the figure are similar*, so ...
long side / hypotenuse = BC/AC = BK/AB
BK = AB(BC/AC) = 12(16/20) = 12×0.8
BK = 9.6

Dude this is a quiz you need to try to do it on ur own
Answer:
Step-by-step explanation:
Represent Anita's age by a and Basilo's by b.
Then a = b - 4.5, and 3(a + 6) = 36 (where I have "invented" the value 3).
Substituting b - 4.5 for a in 3a + 18 = 36: 3(b - 4.5) + 18 = 36
Performing the indicated multiplication:
3b - 13.5 + 18 = 36, or
3b + 13.5 = 18, or
b = 18 - 13.5 = 4.5
Basilo is 4.5 years old, whereas Anita is 9 years old.
