Question

The three Angles in a triangle are given in the ratio of 2:3:5,calculate the size of the smallest angle​

Answer 1

Answer:

2:3;5

2x : 3x : 5x

2x + 3x +5x = 180

10x = 180

x = 18

smallest angle = 2x

so 2x = 2 × x

2 ×18

= 36 degree

pls mark me the brainliest

Answer 2

Answer:

three angle measure 180

then 2x+3x+5x=180

10x=180

x=180/10=18

1. then 2x=( 2)18=36
2. 3x=(3)18=54
3. 5x=(5)18=90
4. then the smallest angle is 36
