The sum of the interior angles of the polygon is 36,000. How much does this polygon have in total diagonal? PLS HELP I CANT FAIL THIS​

I’m not good at math can i have ? ?

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.)

Identify the percent of change as an increase or a decrease. 75 people to 25 people response - correct increase decrease question 2 find the percent of change. round to the nearest tenth of a percent.
