The lengths of two sides of a triangle are shown below: Side 1: 3x² − 4x − 1

Side 2: -x² + 4x + 5

The perimeter of the triangle is 5x³ − 2x² + 3x − 8.

Part A: What is the expression that represents the length of the two sides, 1 and 2, of the triangle?

Part B: What is the expression that represents the length of the third side of the triangle?

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
