Approximate the logarithm using the properties of logarithms, given logb 2 ≈ 0.3562,

logb 3 ≈ 0.5646,

and

logb 5 ≈ 0.8271.

(Round your answer to four decimal places.)

logb(2b^3)

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
