Question

11. The complementary angle
of (x-20) is

a (70+x)°

b (70-x)°

c 90(x+20)°

d (90-x)°​

Answer 1

Step-by-step explanation:

Complementary Angles:

Two angles are called complementary angles, if their sum is one right angle i.e. 90°. Each angle is called the complement of the other. Example, 20° and 70° are complementary angles, because 20° + 70° = 90°. Clearly, 20° is the complement of 70° and 70° is the complement of 20°.

Answer 2

Answer:

[c.]

for example if x is 50... then x-20.=30

now... complementary = 90-×+20

=90-50+20

=40+20

=60

verification.... 30+60=90

hope it helps u

I gave a example to clear u practically

if so mark as brainest:)
