Question

The complement of two fifths of a right angle is .........................

Answer 1

Heya


According to the concept of complementary angles,

x + y = 90 degree

x = 2/5 of 90 degree (given)

x = 36 degree


y =?

Substitute in the first equation,

x + y = 90

36 + y = 90

y = 90-36 = 54 degree


Therfore, the complement of two fifths of a right angle is 54 degree.


Hope this helps

Answer 2

Answer:

54 degrees

Step-by-step explanation:

x + y = 90 degree

x = 2/5 of 90 degree (given)

x = 36 degree

y =?

Substitute in the first equation,

x + y = 90

36 + y = 90

y = 90-36 = 54 degree

Therfore, the complement of two fifths of a right angle is 54 degree.
