Answer:
CPCTC
Step-by-step explanation:
Triangle BUT ≅ triangle ETU. Therefore, by CPCTC (Corresponding Parts of Congruent Triangles are Congruent), we can determine that ∠B ≅ ∠E.

Answer: y = -1/2 x + 3
Step-by-step explanation:
x + 2y= 6 subtract x from both sides
-x -x
2y = 6 - x Divide both sides by 2
y = 3 - 1/2x or y = -1/2x + 3
Answer:
B
Step-by-step explanation:
Base area = (base x width) = 20 x 18 = 360 cm^2
Base perimeter = (base + width) x 2 = (20 + 18) x 2 = 76 cm
lateral surface = (base perimeter x height) = 76 x 15 = 1140 cm^2
Surface area = (base area x 2) + lateral surface = (360 x 2) + 1140= 1860 cm^2
surface area of a single prism = 1860 / 2 = 930 cm^2
This is true
Perpendicular lines = circumscribe
angle bisect = incircle
altitude = orthocenter
median = centriod
