Pythagorean theorem

Mathematics
1 answer:
marta [7]3 years ago

Answer:

x = 8

Step-by-step explanation:

a^{2} +b^{2} =c^{2} \\ so 8^{2} +b^{2} =\sqrt{80} ^{2}

rearrange the formula:

\sqrt{80} ^{2} - 8^{2} = b^{2}

80 - 64 = b^2

b^2 = 16\\b  = \sqrt{16}

\sqrt{16}  = 4

x = 4+4 = 8

ioda
0.5s + 1 = 7 + 4.5s   Subtract 4.5s from both sides
  -4s + 1 = 7              Subtract 1 from both sides
       -4s = 6              Divide both sides by -4
          s = -\frac{6}{4}   Simplify
