Question

in a triangle if the 2nd angle is 5 degrees greater than the 1st angle and 3rd angle is 5 degrees greater than the 2nd angle find the 3 angles of the triangle

Answer 1

Answer:

let the third angle is 3X

so second angle will be 2X {two-third of 3rd angle = 2/3(3X)}

then first angle will be X {half of second angle =1/2(2X)}

in triangle sum of angle = 180° so, 3X + 2X +X =180° 6X = 180° X =30° first angle is
