Answer: -63

Step-by-Step Solution:

=> an = 3 - 6(n - 1)

Hence,
=> a = 3
=> d = -6
=> n = 12

Therefore,
an = 3 - 6(n - 1)
a12 = 3 - 6(12 - 1)
a12 = 3 - 6(11)
a12 = 3 - 66
=> a12 = -63

What is the length of BC in the right triangle below?

gayaneshka [121]

Hey there! :)

Answer:

C. BC = 39 units.

Step-by-step explanation:

Use the Pythagorean theorem to solve for BC. Let BC = c, AB = a, and AC = b.

c² = a² + b²

c² = 15² + 36²

Square and simplify:

c² = 225 + 1296

c² = 1521

c = √1521

c = 39 units.

Therefore:

BC = 39 units.
