Question

I am confused on these 2​

Answer 1

1) x=20 degrees

2) x=25 degrees

Explanation:

1) there is 9x if you add all of the angles together and there is 180 degrees in a triangle so 180 divided by 9 equals 20 degrees.

2)there is 7x and 5 dgress in total so we can make an equation:

7x+5=180

7x=175

x=25
