Mathematics

Write the complement (in degree) of each of the following angles: $20^{\circ}$

70

SOLUTION
As we know for becoming a complementary angle the sum of both the angles should be $90^{\circ}$

Let the complementary angle be $x$

$20^{\circ}+x=90^{\circ}$
$\Rightarrow x=70^{\circ}$

You're just one step away
