Question

The angles of a Pentagon are 6x,(2x+20°),(3x-20°),2x and 14x.Then find x

Answer 1

Answer:

540 = 6x + 2x + 20 + 3x - 20 + 2x + 14x

540 = 8x + 5x + 14x

540 = 8x + 19x

540 = 27x

x = 540 / 27

x = 20

X = 20°

Answer 2

Answer:

The value of x = 20

Step-by-step explanation:

Given,

The five angles of a pentagon are 6x,(2x+20°),(3x-20°),2x and 14x.

To find,

The value of x

Recall the formula

The sum of five angles of a pentagon = 540

Solution:

Since the five angles of the pentagon are 6x,(2x+20°),(3x-20°),2x and 14x

we have

6x+2x+30+3x-20+2x+14x = 540

27x+2 -2 = 540

27x = 540

x = $\frac{540}{27}$

x = 20

The value of x = 20
