Equilateral triangle with the side 4 cm and h=2.5 cm

In equilateral triangle all sides are equal

so all sides are equal in the base of the prism

lateral area of the prism = Perimeter of the base * height

Perimeter of the base equilateral triangle = side + side + side

lateral area of the prism =(side + side + side) * height

= (4+4+4) * 2.5

= 30 cm^2

lateral area of the prism = 30 cm^2

Find the cosine of R.
JulijaS [17]

Answer:

cos(R) = \frac{\sqrt{15}}{5}

Step-by-step explanation:

To find the cosine of <R, apply the following trigonometric ratio formula:

cos(R) = \frac{adjacent}{hypotenuse}

Adjacent = 3

Hypotenuse = √15

Plug in the values into the formula

cos(R) = \frac{3}{\sqrt{15}}

Multiply the numerator and denominator by √15 to rationalize.

cos(R) = \frac{3 \times \sqrt{15}}{\sqrt{15} \times \sqrt{15}}

cos(R) = \frac{3\sqrt{15}}{(\sqrt{15})^2}

cos(R) = \frac{3\sqrt{15}}{15}

cos(R) = \frac{\sqrt{15}}{5}
