What is the area of the triangle below

Ok so you take 13 and multiply it by 10 then divide that product by 2.(13x10)/2= 65 (D.)

Option D is correct.

65 square units

Step-by-step explanation:

Area of right triangle(A) is given by:

     ......[1]

where,

b is the base of the triangle

h is the height of the triangle.

As per the statement:

In the given right angle triangle:

Base(b) = 13 units

Height(h) = 10 units

Substitute in [1] we have;

square units

Therefore, the area of triangle is, 65 square units

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
