Answer 1

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
