Answer:

the coordinates of point K (6, 16)

Step-by-step explanation:

Given the information:

J (0,8).

Let A is the middle point of the line segment => A ( 6, 12).

Let K (a, b)

We have the following formula:

Midpoint(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})\\ where:

J(x_{1},y_{1} )\\K(x_{2},y_{2})

Substitute all the given information, we have:

  • \frac{10+a}{2} = 6

<=> a = 2

  • \frac{8+b}{2} =12

<=> b = 16

=>  the coordinates of point K (6, 16)

Hope it will find you well.

Assoli18 [71]

Answer:

7.36 cm²

Step-by-step explanation:

What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.

The formula for the area of a triangle is given as:

1/2 × Base × Height

Base = 3.2 cm

Height = 4.6 cm

Hence,

Area of the triangle = 1/2 × 3.2 × 4.6

= 7.36 cm²
