A quadrilateral is a polygon that has four sides and four angles. The sum of interior angles in a quadrilateral is 360°. Types of quadrilateral are square, rectangle, rhombus, kite and so on.
Let x represent the length of the third side, hence:
x = 5 + (5 * sin(20)) + (5 * sin(10)) = 7.5 cm
The length of the third side of the quadrilateral is 7.5 cm.

x+142 =3x+64
subtract x from each side
142 = 2x+64
subtract 64 from each side
142-64 = 2x
78=2x
divide by 2
78/2 = x
x=39
The number is 39
Hello! So if Toby makes 7$ an hour and every piece work he makes they pay him 8 cents. And he worked a total of 39 1/2 hours and assembles 203 pairs of sunglasses, First find the anwser to how much money he made in 39 1/2 hours, you multiply 7 by 39 1/2 and you get = 276.50$ dollars. Then 8x203 equals to = 1,624, Lastly you add them up together and you get = 1,900.5$ dollars.
