Question

Find two complementary angles which are 5:4

Answer 1

Answer:

Let the two angles be 4x and 5x

The sum of two complementary angles is 90

∘

∴4x+5x=90

∘

⇒9x=90

∘

⇒x=

9

90

∘

=10

∘

So the angles are 4×10

∘

=40

∘

and 5×10

∘

=50

∘

Answer 2

Answer:

50,40

Step-by-step explanation:

let the angles be 5x and 4x

5x + 4x =90

9x=90

x=90/o

x=10

5x -5 * 10

50

4x- 4*10

40
