Answer:
Step-by-step explanation:
it is 100 times because you have to time 10 times 10 and you get a 100
The two triangles are congruent to each other, meaning they’re proportional to each other but not equal.
The question is asking you to list the angles that are congruent to each other (when talking about angles and congruency, if two angles are congruent, they are equal) and the sides that are congruent to each other (as long as all sides are proportional to each other, they are congruent (Triangle ABC has side lengths of 1, 2, 3 and Triangle DEF has side lengths of 2, 4, 6; these two triangles are congruent))
1) -3•5/ 4•5 And 9•2/ 10•2 Because you want to have the same denominator. That equals -15/20 + 18/20 so you just add -15+18 to get 3/20
The answer is 3/20
