Answer:
3.4
Step-by-step explanation:
both angles are equal, i.e 16x - 9 = 45.
the value of x is 3.375
The value of x is 9.
i used the equation (16x-9) + 45 = 180
1. i added -9 +45 i got 36
2. 16x + 36 = 180
3. i subtract 36 from 36 and 180
4. 16x=144
5. i divide 16 from 16x and 144
6. x=9
I hope this helped! :)
