Question

If angle A=(4X+2)degree find the measure of the complementary of angle A

Answer 1

if sum of any two angles 90 then they are called complementary

A +B =90 let the complement of A is B
4x+2 +B =90
B= 90-4x-2
B = 88-4x
complementary angle = B = 88-4x

Answer 2

If two angles are complementary it means sum of the two angles is equal to 90°
Let the complementary angle of A be B
So,
=>A + B = 90°
=> 4X + 2 + B = 90°
=> B = 90 - 2 - 4X
=> B = 88 - 4X

So, complementary of angle A is (88 - 4X)°
