Answer 1

Answer

Sum of complementary angles is 60°

Let the complement be x

x+60 °=90°

x=30°

sum of suplementary angles is 60°

Let the supplementary angle be y

y+60° = 180°

y= 120°

vertically opposite angle A = 60°

Let the unknown angle be x

sum of the angle of a triangle = 180°

60° + 90° + x = 180°

150° + x = 180°

x = 30°

let two angle be x

sum of angle of equilateral triangle =180°

60° + x +x =180°

60° + 2x = 180°

2x = 120°

x = 60°
