answer a- always
step-by-step explanation: the corresponding angles are congruent and the corresponding sides are proportional with each other. thus, having a pair of similar polygons would mean that its corresponding angles would always be congruent.
where is the triangle?
the area of a right triangle is 1/2 the area of a rectangle with the same dimensions
the triangle has a base of 12 and a height of 5
a rectangle of length 12 and a height 5 will be twice the area
#4 x =
# 5 x = 46.648
+ 36 = 64
= 64 - 36
x = 2
solution for #5 is similar
solve the left side triangle then use that value to solve the triangle on the right.
