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
<span>[x^2/36} + [y^2/9] = 1</span>
FOIL
x^2+11x-9x-99
x^2+2x-99
Hello! Grams would be the correct measurement. One kilogram is equal to about 2.2 pounds. If you cell phone weighed 113 kilograms it would be 249 pounds! The size of an adult!
One gram is about the weight of a paper clip, so it makes more sense for a cell phone to weigh 113 paper clips.
I hope this helps!
