THEOREM:

  • h² = p² + b² where h is hypotenuse, b is base and p is perpendicular.

ANSWER:

[3] By pythagorean theorem,

  • x² = 14² + 9²
  • x² = 196 + 81
  • x² = 277
  • x = √277
  • x = 16.64 rounded.

[4] By pythagorean theorem,

  • x² = 32² + 24²
  • x² = 1024 + 576
  • x² = 1600
  • x = √1600
  • x = 40.

[5] By pythagorean theorem,

  • (2x)² = 21² – 12.6²
  • 4x² = 441 – 158.76
  • 4x² = 284.24
  • x² = 284.24/4 = 70.56
  • x = √70.56
  • x = 8.4

[6] By tangent property,

  • 7x – 29 = 2x + 16
  • 7x – 2x = 16 + 29
  • 5x = 45
  • x = 9.

So, WX = 7(9) – 29 = 63 – 29

  • WX = 34

Isolate the variable by dividing each side by factors that don’t contain the variable.

X = -2

Hope this helps!
