Question

1.) Find the sum of angles of the given polygon by dividing it into triangles

2.) Compute the value of x in the following figure

Answer 1

Step-by-step explanation:

1) sum of angles of the polygon= 5*(sum of angles of triangle)

= 5*(180)

=900°

2) angle ACB= 180°- angle ACD

= angle ACB= 180°-112°

= 68°

Angle ABC + Angle ACB= Angle BAE

angle ABC= 120°-68°

x° = 52°

Answer 2

Answer:

(1)   5 x 180degrees = 900 degrees

(2) 52degrees
