If a right triangle has and angle that is 75 degrees what is the third angle in the triangle?

1 answer

In a right triangle, one of the angles is always 90 degrees. The sum of the angles in any triangle is 180 degrees.

If one angle is 75 degrees, you can find the third angle (let's call it \(C\)) by using the formula:

\[ C = 180^\circ - 90^\circ - 75^\circ \]

Calculating that:

\[ C = 180^\circ - 90^\circ - 75^\circ = 180^\circ - 165^\circ = 15^\circ \]

So, the third angle in the triangle is \(15\) degrees.
