Answer:

<h2>Area = 90 cm²</h2><h2>Perimeter = 53 cm</h2>

Step-by-step explanation:

area and perimeter of the given diagram

<u>area = 1/2 * base * height</u>

where base = 15 cm

height = 12 cm

plugin values into the formula

area = 1/2 * 15 * 12

area = 90 cm²

<u>Perimeter = add up all sides (AB + AC + BC)</u>

where side BC = √(5² + 12²)

BC = 13 cm

Perimeter = 25cm + 15 cm + 13 cm

Perimeter = 53 cm

Solve the equation on the interval [0, 2pi): 12cos^2 x-9=0<br><br><br> What to do?

Answer:

$\large\boxed{x=\dfrac{\pi}{6}\ \vee\ x=\dfrac{5\pi}{6}\ \vee\ x=\dfrac{7\pi}{6}\ \vee\ x=\dfrac{11\pi}{6}}$

Step-by-step explanation:

$12\cos^2x-9=0\qquad\text{add 9 to both sides}\\\\12\cos^2x=9\qquad\text{divide both sides by 12}\\\\\cos^2x=\dfrac{9}{12}\\\\\cos^2x=\dfrac{9:3}{12:3}\\\\\cos^2x=\dfrac{3}{4}\to\cos x=\pm\sqrt{\dfrac{3}{4}}\\\\\cos x=\pm\dfrac{\sqrt3}{2}\\\\\text{Look at the picture}\\\\x=\dfrac{\pi}{6}\ \vee\ x=\dfrac{5\pi}{6}\ \vee\ x=\dfrac{7\pi}{6}\ \vee\ x=\dfrac{11\pi}{6}$
