Question

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

Answer 1

are you sure

Answer 2

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

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

Calculating that:

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

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

Answer 3

Yes, I am sure. Let's go through the calculation again to confirm.

In a right triangle:
1. One angle is a right angle, which is \( 90^\circ \).
2. You have another angle given as \( 65^\circ \).

The sum of the angles in any triangle is \( 180^\circ \). Therefore, you can find the third angle with the following calculation:

\[
\text{Third angle} = 180^\circ - (90^\circ + 65^\circ)
\]

Calculating:

\[
\text{Third angle} = 180^\circ - 155^\circ = 25^\circ
\]

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