Pls answer this two questions tnx!
Answer:
1. ∠A and ∠B are right angles. Given
2. m∠A = m∠ B All right angles are congruent.
3. ∠BEC≅ ∠AED Vertical angles are congruent
4. ΔCBE ~ ΔDAE AA
Step-by-step explanation:
A proof always begins with the givens.
1. ∠A and ∠B are right angles. -------------->Given
2. m∠A = m∠ B are equal since-----------> All right angles are congruent.
3. ∠BEC≅ ∠AED are also equal since---->Vertical angles are congruent
4. ΔCBE ~ ΔDAE since two angles are equal----------> AA
Answer:
Let A and B be the two rocks.
As per the statement: a geologist had two rocks on a scale that weighed 2 1/2 pounds together rock
⇒Total weight of rock () = pounds
or
Also, it is given A weighed a total of of the weight.
⇒
then;
Therefore, pounds did rock A weight.
