a pentagon show each of the following as angle numbers 146, 90, 119, 2x, and 3x+18 find x
To find the value of x in a pentagon, we need to use the property that the sum of the interior angles of a pentagon is equal to 540 degrees.
Given the following angle numbers in the pentagon: 146, 90, 119, 2x, and 3x+18, we can set up the equation:
146 + 90 + 119 + 2x + 3x + 18 = 540
Combine like terms:
373 + 5x = 540
Subtract 373 from both sides:
5x = 167
Divide both sides by 5:
x = 33.4
