Question 461265: on my homework i have a polygon shape and the four interior angles are (5x+30), (10x-10), (8x-1, and (6x-7)... how do i solve for x? Answer by Gogonati(855) (Show Source):
You can put this solution on YOUR website! Since this polygon has four angles it's a rectangle. We know that the sum of interior angles of the rectangle is 360 degree.We write the equation:
, solving this equation we get:x=12.
Answer:The angles of the rectangle are:5*12+30=90; 10*12-10=110; 8*12-1=95 and
6*12-7=65 degree.
