The equation in the form of the given expression is (0)² + (1)² = 1
<h3>Trigonometry identity</h3>
According to some of the trigonometry identity
sin 0 = 0
cos 0 1
Given the expression below
sin^2 0+cos^2 0=1
This can also be expressed as:
(sin0)² + (cos0)² = 1
Substitute
(0)² + (1)² = 1
Hence the equation in the form of the given expression is (0)² + (1)² = 1

Hope it helps.
Complementary means that the two angles sum to 90 degrees.
So based on the problem, let:
1st angle=5x+6
2nd angle=x
Now create an equation.
x+5x+6=90
6x=84
x=14
5x+6=76
answer: 14 degrees and 76 degrees
