Answer:

Z = 13

Step-by-step explanation:

Both of the angles should equal 90.

2z + 5 + 5z - 6 = 7z - 1

7z - 1 = 90

7z - 1 + 1 = 90 + 1

7z = 91

7z ÷ 7 = 91 ÷ 7

Z = 13

Hope that helped you and have a wonderful day!

Answer:

There are 12 possible outcomes.

Step-by-step explanation:

This question represents combined independent events of probability.  Independent events are not affected by previous events.  So, your probability is the same with each flip of the coin or roll of the die.  So, you just have to look at the total number of outcomes for each and multiply them.  Since there are only two sides to a coin, there are only two total outcomes.  Since there are six sides to a die, there are only six total outcomes.  2 x 6 = 12 total outcomes.
