Question

The angles of a quadrilateral are in the ratio 3:4:5:6. How do you find the angles of the quadrilaterals?

Answer 1

In a quadilateral the angles add up to `360^o`

Let's call the angles `3x,4x,5x and 6x`

Then:
`3x+4x+5x+6x=360->`
`18x=360->x=20`

Then the angles are `60^o,80^o, 100^o and 120^o`
(because `3*20=60` etc)

Check: `60+80+100+120=360`
