Georgia [21]4 years ago
8 0

Step-by-step explanation:

With 30°-60°-90° and 45°-45°-90° triangles, the sides have common ratios. The ratios for 30°-60°-90° triangle sides are:

  • x for the smaller side
  • x√(3) for the larger side
  • 2x for the hypotenuse

So 4. for example has a shorter side length of 5 units, which means the longer side is 5√(3) units long, and the hypotenuse is 10 units long.

*For 45°-45°-90° triangles, the ratios are:

  • x for both sides; which have equal lengths
  • x√(2) for the hypotenuse

1+2+2²+2³+...+2^x=1023
mrs_skeptik [129]
1 + 2 + 2^{2} + 2^{3} + 2^{x} = 1023 \\3 + 4 + 8 + 2^{x} = 1023 \\7 + 8 + 2^{x} = 1023 \\15 + 2^{x} = 1023 \\2^{x} = 1023 - 15 \\2^{x} = 1008 \ln(2^{x}) = ln(1008) \\xln(2) = ln(16 * 8 * 7) \\xln(2) = ln(2^{4} * 2^{3} * 7) \\\frac{xln(2)}{ln(2)} = \frac{4ln(2) + 2ln(3) + ln(7)}{ln(2)} \\x = 4 + \frac{2ln(3)}{ln(2)} + \frac{ln(7)}{ln(2)}
