8. The endpoints of ST are s(-3, 2) and t(5,8). Find the coordinates of the midpoint of ST. Then find ST. OA midpoint: (1,5); ST
Naya [18.7K]

Answer:

The mid point of ST is (1,5) and ST = 10 units

Step-by-step explanation:

It is given that,

S(-3,2) and T(5,8). We need to find the coordinates of the midpoint of ST and also ST.

Let (x,y) be the mid point of ST. Using mid-point formula we get :

(x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

We have, x₁ = -3, x₂ = 5, y₁ = 2 and y₂ = 8

So,

(x,y)=(\dfrac{-3+5}{2},\dfrac{2+8}{2})\\\\(x,y)=(1,5)

(1,5) is the midpoint of ST.

Using distance formula to find ST as follows :

ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\ST=\sqrt{(5-(-3))^2+(8-2)^2} \\\\ST=10\ \text{units}

Hence, the mid point of ST is (1,5) and ST = 10 units.

ABCD is an 8 by 6 rectangle. AC is a diagonal with length 10. Point E is on AC such that BE is perpendicular to AC . What is the
anyanavicka [17]

Answer:

The length of BE is 5 units.

Step-by-step explanation:

ABCD is rectangle

AC is a diagonal and BD is a diagonal too.

Diagonals of rectangle are equal and bisect each other perpendicularly.

So, AE = BE

AE = 1/2 × AC

= 1/2 × 10

= 5

BE = 5

Hence the length of BE is 5 units.
