Question

20 pts if you can help this part is for half my grade

Answer 1

Answer:

z = 13 degrees

Step-by-step explanation:

1.) Those two angles add up to 90 degrees, so we can say that 5z - 6 + 2z + 5 = 90

2.) Simplify both sides to get 7z - 1 = 90.

3.) Isolate Variable by adding 1 on both sides to get 7z = 91.

4.) Divide by 7 on both sides to find that z = 13 degrees.

Answer 2

Answer:

z = 13

Step-by-step explanation:

5z - 6 + 2z + 5 = 90

7z - 1 = 90

7z = 91

z = 13
