The answer is 1. it says i need 20 characteristics so I'm just writing this!
Step-by-step explanation:
step 1. so ABC is a triangle.
step 2. interior angles of a triangle add up to 180°
step 3. <A + <B + <C = 180°
step 4. 54 + <B + 74 = 180°
step 5. <B = 52°.
Answer:
-243 gallons of water from the pool
Option B:
ASA congruence
Solution:
Step 1: Given

Step 2: Given

Step 3: Given
(Included side)
Step 4: All right angles are congruent.
(Angle)
Step 5: By vertical angle theorem
(Angle)
Step 6: By ASA congruence
QU and RU are included side of corresponding angles.
Therefore by ASA congruence rule,

Option B is the correct answer.
Hence proved.
