Question

the angles of a triangle are in ratio 2:3:7 find the measure of smallest angle

Answer 1

HEYA!!

Given,

Ratios of angles of triangle are 2:3:7

Let the angles be 2x , 3x and 7x

Sum of all angles in a triangle = 180

ATP,

2x + 3x +7x = 180

12x = 180

x = 180/12

x = 15

first angle :

2x = 2 ( 15 )

= 30

2nd angle :

3x = 3 ( 15 )

= 45

3rd angle :

7x = 7 ( 15 )

= 105 ..

Therefore, the smallest angle = 2x = 2 (15) = 30

Answer 2

hello frnd!!!

here's ur answer....

let the angles of the triangle be 2x, 3x and 7x.

we all know that the sum of interior angles in the triangle is 180°.

therefore 2x+3x+7x=180°

12x=180°

x=180/12

x=15

hence,

1st angle=2x

=2×15

=30°

2nd angle=3x

=3×15

=45°

3rd angle=7x

=7×15

=105°

the smallest angle is 30°

hope this helps u...
