Question

the angle of a triangle are in the ratio 5 4 3 find the measure of each angle

Answer 1

Step-by-step explanation:5+3+4=180 5+3+4=12x

15x =180

75 dg

45°

60°

Answer 2

Answer:

$\red { Measures \: of \:3 \:angles \:are }$

$\green { 75\degree, 60\degree \:and \:45\degree }$

Step-by-step explanation:

$Given \: ratio \: of \: angles \: in \: a \: triangle \\are \: 5:4:3$

$Let \: First \: angle = 5x ,\\Second \:angle = 4x , \\Third \: angle = 3x$

$5x + 4x + 3x = 180\degree$

$\pink {( Angle \: sum \: Property )}$

$\implies 12x = 180\degree$

$\implies x = \frac{180}{12} = 15$

$First \: angle = 5x = 5\times 15 = 75\degree ,\\Second \:angle = 4x = 4\times 15 = 60\degree , \\Third \: angle = 3x = 3\times 15 = 45\degree$

Therefore.,

$\red { Measures \: of \:3 \:angles \:are }$

$\green { 75\degree, 60\degree \:and \:45\degree }$
