What is the value of x and what is angle b?
SashulF [63]

Answer:

x=6

B = 20

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

55+ 3x+2 = 13x-3

Combine like terms

57+3x = 13x -3

Subtract 3x from each side

57+3x-3x = 13x-3x-3

57 = 10x-3

Add 3 to each side

57+3 = 10x-3+3

60 = 10x

Divide each side by 10

60/10 = 10x/10

6 =x

We also want angle B

B = 3x+2

   3*6+2

   18+2

   20

In triangle RST the vertices have coordinates of R(-1,10),S(5,4)and T (-4,-2). If the midpoints of side RS and RT were connected
Effectus [21]

Answer:

\frac{2}{3}

Step-by-step explanation:

Midpoint of a line segment joining points (x,y) and (u,v) is given by (\frac{x+u}{2},\frac{y+v}{2}  )

Points are R(-1,10),S(5,4)and T (-4,-2).

Midpoint of RS = (\frac{-1+5}{2},\frac{10+4}{2}  )=(\frac{4}{2},\frac{14}{2}  )=(2,7 )

Midpoint of RT = (\frac{-1-4}{2},\frac{10-2}{2}  )=(\frac{-5}{2},\frac{8}{2}  )=(\frac{-5}{2},4)

Slope of a line joining points (a,b) and (c,d) is given by \frac{d-b}{c-a}

Slope of line joining midpoints of side RS and RT = (\frac{4-7}{\frac{-5}{2}-2 })=(\frac{-3}{\frac{-9}{2} })=\frac{2}{3}
