Question

Find the sum of angles 1,2,3,4,5 in a star.

a.180

b.300

c.360

d.400

Answer 1

Answer:

a options rightttttt

Step-by-step explanation:

Here we have used a , b , c , d , e in place of 1 ,2 , 3 ,4 , 5

the sum of angles a , b , c , d , e in a star = 180°

Here In picture you can see a triangle

where one angle = a

Other two angles = b + c & d + e

(exterior angle of triangle = Sum of other two interior angles of triangle)

Hence a + b + c + d + e = 180° ( sum of angles of a triangle)

Hence sum of angles a , b , c , d , e in a star = 180°

Answer 2

Step-by-step explanation:

Let the angles be 1x,2x,3x,4x,5x

sum of the angles = 360°

A.T.Q

x+2x+3x4x+5x=360°

15x=360°

x=360/15

= 24°
