What is the area of a triangle with a height of 8 and a base of 8

Area of a triangle: 1/2(base * height)

You are given that the height is 8 units and the base is 8 units, so plug in 8 for the base and height in the formula and solve.

1/2(8 * 8) ⇒ 1/2(64)

1/2(64) = 32

The area of the triangle is 32 units².

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

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
