Step-by-step explanation:
The complement of (90° - a) is a^{\circ}a
∘
Solution:
Given that we have to find complement of (90° - a)
Let us first understand about complement angles
Two Angles are Complementary when they add up to 90 degrees (a Right Angle)
If a and b ( in degrees) are two complement angles, then a + b = 90 degrees
From given information,
One of complement angle = (90° - a)
Let the other complement angle be x
Then by above definition of complementary angles,
\begin{lgathered}\begin{aligned}&90^{\circ}-a+x=90^{\circ}\\\\&-a+x=0\\\\&x=a\end{aligned}\end{lgathered}
90
∘
−a+x=90
∘
−a+x=0
x=a
