Question

100°, 112, 130° and 150°. The Four of the interior angles of a heptagon are ° remaining angles are equal. Find their magnitude.​

Answer 1

Answer:

204°

Step-by-step explanation:

sum of the interior angles = (n-2)×180°

n = number of sides

here, for heptagon

number of sides n = 7

and number of angles = n-1 = 7-1 = 6

sum of interior angles = (7-2)×180° = 900°

Four angles are given and remaining two are equal then,

100° + 112° + 130° + 150° + 2x = 900°

492° +2x = 900°

2x = 408°

x = 204°
