Answer:

 ≈ <em>3.4</em><em> </em>

Step-by-step explanation:

Coordinates of the point that divide segment with endpoints A( x_{1} , y_{1} ) and B( x_{2} , y_{2} ) in a ratio a : b are

\frac{bx_{1} +ax_{2} }{a+b} , \frac{by_{1} +ay_{2} }{a+b} )

A(- 4, - 7)

B(8, - 4)

Ratio 8 : 5

x-coordinate is \frac{5(-4)+8(8)}{8+5} = \frac{44}{13} ≈ <em>3.4</em>

zaharov [31]

Answer:

angle B = 33.42

Step-by-step explanation:

take angle B as reference angle

using tan rule

tan B = opposite/adjacent

tan B = 6/9

tan B = 0.66

B = tan^{-1} (0.66)

B = 33.424

B = 33.42
