6 0

Answer:

x = \frac{2\sqrt{21}}{3}

Step-by-step explanation:

For a 30-60-90 triangle:

  • Short leg = s
  • Long leg = s√3
  • Hypotenuse = 2s

Thus:

  • Short leg = √7/√3 = (√21)/3
  • Long leg = √7
  • Hypotenuse = x = 2(√21)/3

input two pairs of coordinates, we must.

use 0, 1 and 5, 4, we will.

4 - 1 / 5 - 0

3 / 5

3/5, the slope is.

hmm.

convert 3/5 to decimal, we must.

multiply both sides by 2, we can.

3 * 2 = 6

5 * 2 = 10
