To find the measure of the missing angle \( x \) in a right triangle, we first remember that the sum of all angles in any triangle is always 180 degrees. In a right triangle, one angle is always 90 degrees.
The formula can be stated as follows:
\[ \text{Angle A} + \text{Angle B} + \text{Right angle} = 180^\circ \]
If we let Angle A be \( x \) and Angle B be the other angle in the triangle, we can express that as:
\[ x + \text{Angle B} + 90^\circ = 180^\circ \]
This can be rearranged to find the missing angle \( x \):
\[ x + \text{Angle B} = 90^\circ \]
\[ x = 90^\circ - \text{Angle B} \]
Since you have not provided the measure of Angle B, I can't solve for \( x \) directly. However, if you know the measure of the other angle, simply subtract it from 90° to find \( x \).
If you provide the measure of Angle B or confirm the choices (A, B, C, D), I can help determine which option is correct based on that information.
