Answer:

It seems there might be a bit of confusion in the notation you've used. The expression "99⁰ 33° (-x-5)°" is a bit unclear. If you mean an angle in a triangle, let's assume the angles in a triangle are A, B, and C.

If you have two angles given, say A = 99° and B = 33°, and you want to find the third angle C, you can use the fact that the sum of all angles in a triangle is 180°:

\[ A + B + C = 180° \]

Substitute the known values:

\[ 99° + 33° + C = 180° \]

Now, solve for C:

\[ C = 180° - 99° - 33° \]

\[ C = 48° \]

So, in this case, the third angle (angle C) is 48°.

Answer:

The sum of the interior angles of a triangle is always 180 degrees. To solve for the unknown angle in the triangle given the information you provided, you can use the fact that the sum of the angles in a triangle is 180 degrees.

Let's denote the angles in the triangle as follows:

Angle 1 = 99 degrees

Angle 2 = 33 degrees

Angle 3 = \(x - 5\) degrees

Now, to find the value of \(x\) for the third angle:

\[99^\circ + 33^\circ + (x - 5)^\circ = 180^\circ\]

Combine the known angles:

\[132^\circ + (x - 5)^\circ = 180^\circ\]

To solve for \(x\):

\[x - 5 = 180^\circ - 132^\circ\]

\[x - 5 = 48^\circ\]

\[x = 48^\circ + 5^\circ\]

\[x = 53^\circ\]

Therefore, the third angle \(x - 5\) is \(53^\circ\) degrees.
