Answer:

\large\boxed{\left(-\dfrac{1}{2},\ -1\right)}

Step-by-step explanation:

\text{The formula of a midpoint:}\\\\\left(\dfrac{x_1+x_2}{2};\ \dfrac{y_1+y_2}{2}\right)\\\\================================\\\\A(1,\ -3),\ B(-2,\ 1)\\\\\text{Substitute:}\\\\x=\dfrac{1+(-2)}{2}=\dfrac{-1}{2}=-\dfrac{1}{2}\\\\y=\dfrac{-3+1}{2}=\dfrac{-2}{2}=-1

Answer:

(\frac{-1}{2} ,-1)

Step-by-step explanation:

line segment AB has endpoints A(1,-3) and B(-2,1).

To find the midpoint of AB we use formula

(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

A(1,-3) is (x1,y1) , B(-2,1) is (x2,y2)

Plug in the values in the formula

(\frac{1-2}{2} ,\frac{-3+1}{2} )

(\frac{-1}{2} ,\frac{-2}{2} )

(\frac{-1}{2} ,-1)

Answer:

Since we have a 30° - 60° - 90° triangle, we can calculate any side by knowing at least one out of three:

Since the length of the hypotenuse is twice as long as the shorter leg, we have:

The length of the short leg is: 25/2 = 12.5

Since the length of the longer leg is equal to the length of the shorter leg

multiply by square root of 3 we have:

The length of the longer leg is: 12.5 × √3 ≈21.65

=> The perimeter of the triangle is: 25 + 12.5 + 21.65 = 59.15
