Question

the angles of traingle are (x-21), x and (2x-45). find the value of x?​

Answer 1

Answer:

by angle sum property we know that

sum of all angles of a triangle is 180°

so here

(x-21) + (x) + (2x-45) = 180°

x-21 + x + 2x -45 = 180°

4x - 66 = 180°

4x = 180° + 66

4x = 246

x = 246/4

x= 61.5
