The lines y = x and x = a enclose a triangle with the x- and y-axes.
a) Find the area of the triangle when a = 5

Respuesta :

Answer: 12.5

Step-by-step explanation:

As y=x has a slope of 1, it will intersect the line x = 5 at a value of 5, creating an isocoles right triangle with leg length 5. The area of a triangle = (b*h)/2. (5*5)/2 = 12.5 square units
