Answer:

39.9

Step-by-step explanation:

a/sinA = c/sinC

a/sin(77) = 16/sin(23)

a = sin(77) × 16/sin(23)

a = 39.89935764

(-1,8) and (8,5). this is a coordinate distance wuestion that i rly need help on
Inga [223]

Answer:

3\sqrt{10} ≈ 9.45

Step-by-step explanation:

calculate the distance d between the points using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 1, 8 ) and (x₂, y₂ ) = (8, 5 )

d = \sqrt{(8-(-1))^2+(5-8)^2}

   = \sqrt{(8+1)^2+(-3)^2}

   = \sqrt{9^2+9}

   = \sqrt{81+9}

   = \sqrt{90}

   = \sqrt{9(10)}

   = \sqrt{9} × \sqrt{10}

   = 3\sqrt{10} ← exact value

   ≈ 9.49 ( to 2 dec. places )
