A=lw
l=10 feet
w=8 feet
A=8*10
A=80 feet
The answer is 13, use the function p(w)=-4500+350w
Using rigid motion, both of these triangles will be congruent. The reason is because rigid motions include reflections, translations, and rotations.
None of these transformations will affect the size or shape of the figure, therefore keeping them congruent.
Similar triangles have equal angles. I mean, if two triangles
are similar, then the angles of one triangle are the same as
the angles of the other one.
The triangle in the question has angles of 20° and 40°.
The angles of every triangle add up to 180°, so we know
that the third angle has to be 120°
If another triangle is similar to this one, then the other one
also has angles of 20°, 40°, and 120°.
