Let x represent the shorter sides, then 2x + 1 would represent the longer sides. There are four short sides and two long sides. The perimeter is 162 cm. The equation: 4x + 2(2x + 1) = 162 4x + 8x + 2 = 162 8x + 2 = 162 Subtract 2 from both sides. 8x = 160 Divide both sides by 8. x = 20 The shorter sides are 20 cm in length. The longer sides are 2x + 1, or 41 cm in length. Check: 4 * 20 + 2 * 41 = 162 80 + 82 = 162 162 = 162, values check.
As the front approaches, you will have a storm.

Answer:
A triangle is a total of 180 degrees
So to find what x equals we are going to add up all the degree measurements and make them equal to 180
3x+2x+20+4x-20=180 (combine any like terms on the left)
3x+2x+4x+20-20=180 (3x+2x+4x=9x, 20-20=0)
9x=180 (divide both sides by 9)
x=20
