A rectangluar pyramid of height 9 km
measuring 6 km and 11 km along the base

Find the slope of the line y =8/9x + 1.

Can someone answer it, and plot it, for 20 points and brainliest answer? p.s. they're the same ! : )

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
