Question

Helpppp please Metall!!
2. In triangle ABC, A is a right angle, and mB = 45°. Find BC. If your answer is not an integer, leave it in simplest radical form.

The diagram is not drawn to scale. (1 point)

Answer 1

use a trig function.

Answer 2

whats that

Answer 3

\[\sin 45 = \frac{ 12 }{ BC }\]

Answer 4

\[12\sqrt{2}\]

Answer 5

If you have that right angle shown, and you are given angle B is 45 degrees, then that also means angle C is 45 degrees. If you have a 45-45-90 triangle, then the ratio of the base to the height = 1, right? So if we know CA is 12, then BA also must be 12, so then you can just use pythag theorem to get the hyp.

Answer 6

\[\Large BC = 12\sqrt{2}\] is correct
