Question

the angle of triangle are in the ratio 3:2:7find each angle​

Answer 1

Step-by-step explanation:

$|given| \\ the \: angles \: of \: triangle \: are \: in \: ratio \: = 3: 2: 7 \\ \: let \: be \: the \: angles \: of \: triangle \: = x \\ the \: sum \: of \: all \: angles \: of \: triangle \: = 180 ° \\ to \: find: \\ \\ each \: angles \\ \\ 3x + 2x + 7x = 180° \\ 12x = 180° \\ x = \frac{180}{12} \\ x = 15° \\ first \: angle \: = 3x = 3 \times 15 = 45° \\ second \: angle = 2x = 2 \times 15 = 30° \\ third \: angle = 7x = 7 \times 15 = 105°$
