Use the image to answer the question.
An illustration shows three rays D, G, and F emerging from a point labeled E, forming a right angle at E. The right angle is divided into two parts by ray E G. The angles face leftward. Angle D E F measures 90 degree, angle D E G measures left parenthesis 2 x right parenthesis degrees, and angle G E F measures left parenthesis 5 x minus 22 right parenthesis degrees.

To find the value of x, we can set up the equation:
25 + 5x = 90
Now we can solve for x by subtracting 25 from both sides:
5x = 65
Dividing both sides by 5:
x = 13
Therefore, the value of x is 13.
25 + 5x = 90
Now we can solve for x by subtracting 25 from both sides:
5x = 65
Dividing both sides by 5:
x = 13
Therefore, the value of x is 13.

To find the two angle measures of complementary angles expressed as 3x° and (2x−5)°, we can set up the equation:
3x + (2x-5) = 90
Now we can solve for x:
5x - 5 = 90
5x = 95
x = 19
Substituting the value of x back into the expressions for the angle measures:
3(19) = 57°
2(19) - 5 = 33°
Therefore, the two angle measures are 57° and 33°.
3x + (2x-5) = 90
Now we can solve for x:
5x - 5 = 90
5x = 95
x = 19
Substituting the value of x back into the expressions for the angle measures:
3(19) = 57°
2(19) - 5 = 33°
Therefore, the two angle measures are 57° and 33°.

To find the value of x, we can set up the equation:
40 + (8x + 2) = 90
Now we can solve for x by subtracting 40 from both sides:
8x + 2 = 50
Subtracting 2 from both sides:
8x = 48
Dividing both sides by 8:
x = 6
Therefore, the value of x is 6.
40 + (8x + 2) = 90
Now we can solve for x by subtracting 40 from both sides:
8x + 2 = 50
Subtracting 2 from both sides:
8x = 48
Dividing both sides by 8:
x = 6
Therefore, the value of x is 6.
