a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?

viktelen [127]

Answer:

The area of the right triangle is 100 centimeters squared.

Step-by-step explanation:

The formula for the area of a right triangle is:

$Area = \frac{a*b}{2}$

Area = (a*b) / 2

The height of a triangle is represented by a. The base is represented by b.

Knowing this, we can use what they give us for the values, by plugging them into the formula.

a is 20 cenimeters

b is 10 centimeters

Therefore :

$Area = \frac{200}{2}$

$Area = 100$

So, the area of the right triangle is 100 centimeters squared.

2. JI. has coordinates J(-6, 1) and Z(-4, 3). Find the coordinates of the midpoint.

AleksandrR [38]

Answer:

(- 5, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

Here (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 4, 3) thus

midpoint = $\frac{-6-4}{2}$ , $\frac{1+3}{2}$ ) = ( $\frac{-10}{2}$ , $\frac{4}{2}$ ) = (- 5, 2 )
