let the smallest even number be x, than the four even numbers are x, x+2, x+4, x+6, their sum is 180
x+x+2+x+4+x+6=180
4x+12=180

Applying the definition of complementary angles, the value of x in the figure given is: 12
<h3>What are Complementary Angles?</h3>
Complementary angles are angles that give 90 degrees when added up.
(3x + 6) + 48 = 90 [definition of complementary angles]
Solve for x
3x + 54 = 90
3x = 90 - 54
3x = 36
x = 36/3
x = 12
