Round answers to the nearest hundredths.
Splitting the trapezoid into 2
triangles and a
we
can sum up the areas to find the area of the trapezoid. The area of each right triangle
is
square units. The area of the rectangle is
square
units. The area of the trapezoid is
square units.
answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°
so ac is the half of 24=12ft,and from the pythagorean theorem we find ba
ba=√bc^2-ac^2=√576-144=√432=12√3ft
so bac is 12+12√3=12(1+√3)ft

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m
