Question

if one of the angle of triangle is 65 degree and the other two angle are in ratio 2 : 3 find other two angle​

Answer 1

$65 + 2x + 3x = 180 \\ 65 + 5x = 180 \\ 5(13 + x) = 180 \\ 13 + x = 36 \\ = > x = 23 \\ \\ \\ \\ \\ \\ = = = > 2x = 46 \\ \\ \\ \\ \\ \\ = = = > 3x = 69$

Answer 2

Answer:

one angle=65°

another two let be2x, 3x

than

2x+3x=5x

and 180°-65°=115°

5x=115°x

x=115/5=23°

2x=23×2=46°

3x=23×3=69°

hence, 65+46+69=180°
