Question

find complement angle of 40°​

Answer 1

Answer:

50 degree

sum of complementary angle is equal to 90degree

first angle is 40degree

let's second one is X

lets arrange the values according to formula ..

40+X =90

X =90-40

X =50

hence the complement angle of 40° is 50°

Answer 2

Answer:

50°

Concept:

Complementary angles are the angles whose sum is 90°.

Step-by-step explanation:

Let the complement of 40° be x°.

Now, as 40° and x° are complementary angles,

their sum equals 90°.

40° + x° = 90°

x° = 90° - 40°

x° = 50°

Therefore, the complement of 40° is 50°.
