Question

A, B and C are in the ratio 4 : 5 : 6. If B = 120, find A and C.​

Answer 1

Step-by-step explanation:

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:

so that division by 4 in 120. and 5 division in 120 and 6 is divided in 120 all ratio +4+5+6 =16
