Question

If a right triangle has an angle that is 65°, what is the third angle in the triangle? (1 point)
15°
25°
35°
45°

Answer 1

In a right triangle, one of the angles is 90°. The sum of the angles in any triangle is always 180°. Therefore, to find the third angle given that one angle is 65°, you can use the following equation:

\[
\text{Third angle} = 180° - 90° - 65°
\]

Calculating this gives:

\[
\text{Third angle} = 180° - 90° - 65° = 180° - 155° = 25°
\]

So the third angle in the triangle is **25°**.
