Answer:

B

Step-by-step explanation:

Using the Sine Rule in ΔABC

\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}

∠C = 180° - (82 + 58)° = 180° - 140° = 40°

Completing values in the above formula gives

\frac{a}{sin58} = \frac{b}{sin82} = \frac{8.4}{sin40}

We require a pair of ratios which contain b and 3 known quantities, that is

\frac{b}{sin82} = \frac{8.4}{sin40}

OR

\frac{sin40}{8.4} = \frac{sin82}{b} → B

The midpoint of AB is M(7. – 7). If the coordinates of A are (8,-6), what are the
IRISSAK [1]

Answer: B = (6,-8)

Step-by-step explanation:

first the midpoint formula is (\frac{x1+x2}{2},\frac{y1+y2}{2})

then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:

\frac{8+x}{2}=7

then solve it like an equation:

8+ x=14\\x=6

then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:

\frac{-6+y}{2} =-7

then solve it like an equation:

-6+y=-14\\y=-8

∴ the answer is x=6, y= -8

which is expressed as a point, B(6,-8)
