A trapezoid is a quadrilateral which means the sum of the angles should be equal to 360 degrees. The other angles therefore should have the sum of 360 - 60 - 45 = 255 degrees. Since we do not have the figure it would be hard to specify the measure of each angle.
According to the question, the equation 
is the algebraic equation as well as polynomial equation. Using square root principles, the equation can be re-write.
The factors of the denominator term is not possible and it cannot be simplified. And the simplification is possible with the concept of complex number.
What is polynomial expression?
Polynomial expression are those equation whose highest degree is two. It is also called as quadratic equation. And it is simplified by performing the factors on the given expressions.

My answer would probably be 10 because draw a line between the equal sign and the opposite of + is subtract and put it by the 17 so x=10
The rational number, 5/7 converted to a decimal is 0.714.
<h3>What is the decimal?</h3>
A rational number is a number that can be expressed as a fraction of two integers.
A decimal is a non-integer in which the integers are separated from the non integers by a point. In order to convert the fraction to a decimal, divide the numerator by the denominator.
5/7 = 0.714
