<h2>In triangle BDE and triangle BAC</h2><h2>Angle B = Angle B (Common) </h2><h2>Angle BDE = Angle BAC </h2><h2>Therefore, triangle BDE is congruent to triangle BAC (AA similarity) </h2><h2>Hence proved. </h2>
Hope it helps :)
Answer: The domain is the set of all possible x-values in the graph and the range is the set of all possible y-values in the graph. Incorrect. To determine the range, identify the set of all possible y-values in the graph. The minimum y-value on this graph is 4.
any more help just ask:)
one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
