Question

if the angles of a rectangles quadrilateral in ratio 5:8:11::12, find the angles of the quadrilateral ​

Answer 1

[tex]\huge \mathfrak{ Answer:-} \\ Let \: the \: angles \: be \: x. \\ According \: to \: the \: question , \\ Angle \: sum \: propert \\ 5x + 8x + 11x + 12x = 360° \\ 36x = 360° \\ x = \frac{360}{36 } \\ x = 10° \\ 5x = 5(10) = 50° \\ 8x = 8(10) = 80° \\ 11x = 11(10) = 110° \\ 12x = 12(10) = 120° \\ Therefore, \: the \: angles \: of \: the \: quadrilateral \: are \:

50°, \: 80°, \: 110°, \: 120 °.[/tex]
