Sample problems demonstrating the use of triangle properties and algebra to solve for unknown variables.
A diagram showing two sample problems involving triangles and algebraic equations to find the value of n. Problem 2a shows a right triangle with sides labeled 3n and 54, and Problem 2b shows an isosceles triangle with side labeled n-9 and base 46. Problem 3 shows a house roof diagram with a support height x and a total height of 3 ft, with the equation 2x = 3 ft.
