Given: and are right angles; ; prove: step 1: we know that because all right angles are congruent. step 2: we know that because corresponding angles of parallel lines are congruent. step 3: we know that because it is given. step 4: because of the asa congruence theorem. aas congruence theorem. third angle theorem. reflexive property.

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
