Question

find the angle which is equal to it's complement find the third angle​

Answer 1

Answer:

Let

one of the two equal complementary angles be x.

∴x+x=90

o

⇒2x=90

o

⇒x=

2

90

o

=45

o

Thus, 45

o

is equal to its complement.

Answer 2

Step-by-step explanation:

Let the angle be x.

And its complement angle be y

By the problem x= 2y/3

We know that,

Sum of complementary angles is 90

⇒y+ 2y/3=90

⇒ 3y+2y/3 =90

⇒5y/3 =90

⇒5y=90×3

y=90x3/5

y=36

Therefore,

The angles are 54 ,36
