Question

Are the following pairs of angles complementary
(iii) 54° and 2 fifth
of a right angle​

Answer 1

Answer:

Yes.

Step-by-step explanation:

2/5 of 90° = 2*90°/5

=180°/5

=36°

Now, complementary angles means, they sum up to 90°

So, 54°+36° = 90°

∴54° and 2 fifth of right angle sum up to 90° which are complementary.

Answer 2

Step-by-step explanation:

Complementary angles add up to 90 degrees

1st angle = 54 ( given)

2nd angle = 2/5 of right angle

2/5 x 90 ( right angle measures 90)

180/5 = 36

Sum of both the angles = 54 + 36 = 90

Yes, the pair of given angles are complementary.
