Question

Give the solution
$if \: the \: angles \: of \: a \: triangle \: are \: in \: the \: ratio \: 2:3:4 \: then \: the \: measure \: of \: the \: greatest \: angle \: is ?$

Answer 1

hlo mate.

here is your answer.

____________________
$let \: the \: numbes \: be \: 2x \: 3x \: and \: 4x \\ \\ \\ 2x + 3x + 4x = 180(angle \: sum \: property \: ) \\ \\ \\ 9x = 180 \\ x = 180 \div 9 \\ = 20$

let us find the value of each of the angles. .
2x=2×20
=40.

3x=3×20
=60. .
4x=4×20
=80

.......hence the value of the greatest angle is 80 degree. .

Answer 2

$\huge \blue{let}$

The angle be 'x'

Then

According to problem

=> 2x + 3x + 4x = 180°
[sum of angle of a triangle is 180° ]

=> 9x = 180°

=> x = 180/9

=> x = 20°

Then angles are 2x => 20 x 2 = 40°

3x => 3 x 20 = 60°

4x => 4 x 20 = 80°
