Sandys high school played 18 games this year and were defeated during 4 games how many did they win ?

What is the area of triangle abc if a = 8, b = 11, and c = 15?

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

Iwill give you ! what is the measure of ∠v ?
