In a right triangle, the sum of all angles is 180 degrees. Since one angle is a right angle (90 degrees), the sum of the remaining two acute angles must be 90 degrees.

Given the acute angles measure \( 2x + 6 \) degrees and \( 3x - 26 \) degrees, we can set up the equation:

\[ (2x + 6) + (3x - 26) = 90 \]

Now, simplify the equation:

  1. Combine like terms: \[ 2x + 3x + 6 - 26 = 90 \]

This simplifies to: \[ 5x - 20 = 90 \]

  1. Next, add 20 to both sides: \[ 5x = 110 \]

  2. Now, divide by 5: \[ x = 22 \]

Now that we have the value of \( x \), we can find the measures of the two acute angles:

  1. For the first angle: \[ 2x + 6 = 2(22) + 6 = 44 + 6 = 50 \text{ degrees} \]

  2. For the second angle: \[ 3x - 26 = 3(22) - 26 = 66 - 26 = 40 \text{ degrees} \]

Thus, the measures of the angles in the triangle are:

  • \( 50 \) degrees
  • \( 40 \) degrees
  • \( 90 \) degrees (the right angle)

In summary:

  • The two acute angles are 50 degrees and 40 degrees. The right angle is 90 degrees.
