Work out the angle of x please answer ASAP!!
geniusboy [140]

Given:

The figure of a pentagon.

To find:

The value of the x.

Solution:

We know that, the sum of all interior angles of a pentagon is 540 degrees. So,

(5x-25)+(6x+25)+(6x-3)+(9x)+(7x+15)=540

(5x+6x+6x+9x+7x)+(-25+25-3+15)=540

33x+12=540

Subtract both sides by 12.

33x+12-12=540-12

33x=528

Divide both sides by 33.

x=\dfrac{528}{33}

x=16

Therefore, the value of the x is 16.

Simplify the expression 2.75j+2.25-1.5j+3
scoray [572]
The answer is 1.25j + 5.25 

2.75j + 2.25 - 1.5j + 3

2.75j - 1.5j + 2.25 + 3

1.25j + 5.25 

You can't do anymore with this so therefore this would be the answer. 

I hope this helped! : )
