Δ YX Z And Δ VUW are SIMILAR because all their respective angles are congruent:
∠ y = 90°; ∠ v = 90°
∠ x = 67°; ∠ u = 67°
∠ z = 23°; ∠ w = 23°
Two triangles are similar if their related angles are congruent (answer B)
Answer:
The fencing Chaz used for the pen is 56.67 feet
Step-by-step explanation:
Fencing interprets to circumference
If the radius of the pen is 9 ft
