Question

If the angle of a triangle are in ratio 3:8:9 then their respective degree measures are​

Answer 1

Step-by-step explanation:

We Have :-

$Angles \: of \: a \: triangle \: are \: in \: the \: ratio \: 3:8:9$

To Find :-

$Angles$

Solution :-

$Let \: the \: angles \: be \: 3x ,\: 8x, \: 9x \\ \\ \\ We \: know \: that \: sum \: of \: all \: angles \: in \: a \: triangle \: is \: 180 \\ \\ \\ This \: is \: known \: as \: Angle \:Sum \: Property \\ \\ \\ 3x + 8x + 9x = 180 \\ \\ \\ 20x = 180 \\ \\ \\ x = \dfrac{180}{20} \\ \\ \\ x = 9 \\ \\ \\ 3x = 3 \times 9 = 27 \\ \\ \\ 8x = 8 \times 9 = 72 \\ \\ \\ 9x = 9 \times 9 = 81 \\ \\ \\ Angles \: are \: 27 ,\: 72 ,\: 81$
