Question

One angle of an octagon is 65º. Theothers are equal to each other. Find them.​

Answer 1

Answer:

42 1/7 degrees

Step-by-step explanation:

65+7x=360

7x=295

x=42 1/7

Answer 2

• Answer:

x = 145°

• Step-by-step explanation:

the sum of interior angles of octagon formula

S = (n - 2)×180°

n = 8

S = (8 - 2)×180°

S = 6×180°

S = 1080°

we have 1 angle = 65° & others are equal to each other

1080° - 65° = 7x

7x = 1015°

x = 1015° : 7

x = 145°
