A triangular pyramid has a volume of 1333. yd
What are the possible measures of the area of the base, B, and the
height, h, of the pyramid? (Recall the formula V -
- Bh)
O B = 50 cm2:n = 10 cm
OB = 50 cm2:n = 30 cm
B = 100 cm2, n = 10 cm
OB = 100 cm2, n = 30 cm

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
