Question

three angles of heptagon are 82 degree ,110 degree and 30 degree if the remaining four angles are equal find the measure of each equal angle​

Answer 1

total no. of sides of a heptagon =7

total interior angles of a heptagon=180(7-2)

= 180×5 = 900

let the equal angle be x

x+x+x+x+80+110+130=900

4x=900-320

x=145 please follow me
