<h3>Solution:</h3>
  • The sum of all the angles which stand on a straight line is 180°.
  • Therefore,
  • 2z + 140° = 180°
  • or, 2z = 180° - 140°
  • or, 2z = 40°
  • or, z = 40° ÷ 2
  • or, z = 20°
<h3>Answer:</h3>

z = 20°

Hope it helps! Please do comment if you have any query.

Thank you

180-140=40 (complementary angle)

First you need to find the area, the formula is A=LxW, multiply 14 by 11, that’s the area. If one back covers 22 ft we need to find how many 22s are in 154, to do that you divide. Make sense?
